Up supports:\n\n- Super easy [topic: tables]\n- [Topic: revealable content] (e.g. spoilers)\n- [Topic: description lists]\n- [Topic: overlapping]\n- So much more!\n\nFor software developers, Up offers a software library that converts Up markup into HTML. To learn more, please see [topic: using the Up library].\n\n\n\n===========\nWhy use Up?\n===========\n\nUp isn’t the only markup language that produces HTML. What makes it special?\n\n\nUp has a flexible, forgiving syntax\n===================================\n\nUp recognizes [topic: numbered lists] that count backwards.\n\nMarkup\n ````\n 3) Buy milk\n 2) Buy bread\n #) Buy happiness\n ````\n\nOutput\n 3) Buy milk\n 2) Buy bread\n #) Buy happiness\n\nUp usually ignores [topic: excessive delimiter characters].\n\nFor example, you don’t need to perfectly balance asterisks when stressing or emphasizing text.\n\nMarkup\n ````\n I ***love****** asterisks!\n ````\n\nOutput\n I ***love****** asterisks!\n\nUp isn’t picky about which brackets you use for [topic: links].\n\nMarkup\n ````\n - Buy [milk] (en.wikipedia.org/wiki/Milk)\n - Buy (bread) [en.wikipedia.org/wiki/Bread]\n - Buy [sugar] [en.wikipedia.org/wiki/Sugar]\n - Buy (happiness) (en.wikipedia.org/wiki/Happiness)\n ````\n\nOutput\n - Buy [milk] (en.wikipedia.org/wiki/Milk)\n - Buy (bread) [en.wikipedia.org/wiki/Bread]\n - Buy [sugar] [en.wikipedia.org/wiki/Sugar]\n - Buy (happiness) (en.wikipedia.org/wiki/Happiness)\n\nUp even supports [topic: overlapping]!\n\nMarkup\n ````\n John **enjoys ==sleeping** late== whenever he can.\n ````\n\nOutput\n John **enjoys ==sleeping** late== whenever he can.\n\n\nUp uses customizable keywords\n=============================\n\nToo many markup languages devolve into a dense soup of symbols and punctuation.\n\nWhen a keyword would provide more clarity than a symbol, Up takes advantage of that! Several writing conventions, including [topic: tables] and [topic: revealable content], incorporate keywords.\n\nIf you’re a software developer using the Up library, you can provide multiple custom variations for each keyword. To learn more, please see [topic: customizing keywords].\n\n\nUp produces fully accessible HTML\n=================================\n\nFrom the table of contents to the last movie-ruining spoiler, Up produces fully accessible HTML. This means folks who might struggle to view a screen or a use mouse can enjoy every document.\n\n\n\n=================\nWhy *not* use Up?\n=================\n\nYou want a rich ecosystem of tools\n==================================\n\nThere is only one [software library for Up] (npmjs.com/package/@xcvz/up), written and maintained by only one [person] (github.com/start). In contrast, [other markup languages] (duckduckgo.com/?q=markdown) have countless tools and plugins.\n\n\nYou need speed\n==============\n\nUp is not terribly slow, but it’s not terribly fast, either---at least not yet! If you need instant, real-time parsing and rendering of large documents, Up isn’t the best markup language for you.\n\n\n\n###################\nWriting conventions\n###################\n\nDon’t get lost! The following terms are occasionally used throughout this section.\n\nWriting convention\n Any special annotation or formatting recognized by Up.\n\nInline writing convention\n Any writing convention that can be used within paragraphs. This includes [topic: emphasis] and [topic: highlighting].\n\nOutline writing convention\n Any non-inline writing convention. This includes [topic: paragraphs] and [topic: tables].\n\n\n==========\nParagraphs\n==========\n\nParagraphs are the simplest writing convention in Up.\n\nMarkup\n ````\n Unlike regular dental floss, floss picks are easy to use even if you’re not a trained dental hygienist.\n\n Floss picks are sold in stylish, resealable plastic bags. Buy some today!\n ````\n\nOutput\n Unlike regular dental floss, floss picks are easy to use even if you’re not a trained dental hygienist.\n\n Floss picks are sold in stylish, resealable plastic bags. Buy some today!\n\nTo produce a paragraph, write a line of text. That’s all there is to it!\n\nTypically, paragraphs are separated by one or two blank lines. Three or more blank lines between paragraphs indicate a meaningful change of subject. To learn more, see [topic: thematic breaks].\n\nIn contrast, *consecutive* non-blank lines produce [topic: line blocks], not consecutive paragraphs.\n\n\n===========\nLine blocks\n===========\n\nUse the line block convention for addresses, lyrics, or anything consisting of *lines* instead of actual [topic: paragraphs].\n\nMarkup\n ````\n Have you read my new poem?\n\n Roses are red\n Violets *aren’t* blue\n Lyrics have lines\n And addresses do, too\n\n Poetry is just too easy.\n ````\n\nOutput\n Have you read my new poem?\n\n Roses are red\n Violets *aren’t* blue\n Lyrics have lines\n And addresses do, too\n\n Poetry is just too easy.\n\nConsecutive non-blank lines produce a line block, unless those lines represent another writing convention, like [topic: numbered lists].\n\n\n========\nEmphasis\n========\n\nUse the emphasis convention to emphasize a word or phrase.\n\nIf the reader should pronounce a word or phrase differently (e.g. to indicate contrast or sarcasm), consider emphasizing it.\n\nMarkup\n ````\n Only eat the *green* grapes. The red grapes are for Pikachu.\n ````\n\nOutput\n Only eat the *green* grapes. The red grapes are for Pikachu.\n\nTo emphasize text, enclose it within single asterisks.\n\nLike most inline writing conventions, emphasis can be nested within itself.\n\nMarkup\n ````\n John really, *really, *really** hates Red Delicious apples.\n ````\n\nOutput\n John really, *really, *really** hates Red Delicious apples.\n\n\n======\nStress\n======\n\nUse the stress convention to indicate a word or phrase is particularly important.\n\nIf the reader should raise their voice while reading a word or phrase, consider stressing it.\n\nMarkup\n ````\n Do **not** step on the dinosaur!\n ````\n\nOutput\n Do **not** step on the dinosaur!\n\nTo stress text, enclose it within double asterisks.\n\nLike most inline writing conventions, stress can be nested within itself.\n\nMarkup\n ````\n John really, **really, **really**** hates Red Delicious apples.\n ````\n\nOutput\n John really, **really, **really**** hates Red Delicious apples.\n\n\n=======\nItalics\n=======\n\nUse the italic convention to stylistically offset a word or phrase from the surrounding text *without* conveying emphasis. The titles of books and movies should probably be italicized.\n\nIf you want to emphasize text, see [topic: emphasis].\n\nMarkup\n ````\n My favorite video game is _Chrono Cross_.\n ````\n\nOutput\n My favorite video game is _Chrono Cross_.\n\nTo italicize text, enclose it within single underscores.\n\nLike most inline writing conventions, italicized text can be nested within itself.\n\nMarkup\n ````\n My favorite show is _Real Recipes _Redux_: Super Suppers_.\n ````\n\nOutput\n My favorite show is _Real Recipes _Redux_: Super Suppers_.\n\n\n====\nBold\n====\n\nTypically, people use bold text to convey extra importance---but that’s what the [topic: stress] convention is for!\n\nTo make a word or phrase bold *without* conveying any extra importance, use the plain old bold convention.\n\nMarkup\n ````\n Has anyone actually used __KABOOM__ cleaning products?\n ````\n\nOutput\n Has anyone actually used __KABOOM__ cleaning products?\n\nTo make text bold, enclose it within double underscores.\n\nLike most inline writing conventions, bold text can be nested within itself.\n\nMarkup\n ````\n We’ve all seen the ads.\n\n __No hard scrubbing! __KABOOM__... and the stains are gone!__\n ````\n\nOutput\n We’ve all seen the ads.\n\n __No hard scrubbing! __KABOOM__... and the stains are gone!__\n\n\n============\nHighlighting\n============\n\nTo draw attention to text *without* strictly altering its semantics, use the highlighting convention.\n\n(Generally, highlighting shouldn’t be used to emphasize or stress text. If that’s your purpose, see [topic: emphasis] or [topic: stress].)\n\nMarkup\n ````\n Our cupcakes are organic, ==gluten-free==, and made using only the most expensive ingredients.\n ````\n\nOutput\n Our cupcakes are organic, ==gluten-free==, and made using only the most expensive ingredients.\n\nTo highlight text, enclose it within two or more equal signs.\n\nLike most inline writing conventions, highlighting can be nested within itself.\n\nMarkup\n ````\n Our cupcakes are ==organic, ==gluten-free==, vegan==, and made using only the most expensive ingredients.\n ````\n\nOutput\n Our cupcakes are ==organic, ==gluten-free==, vegan==, and made using only the most expensive ingredients.\n\n\n=====\nLinks\n=====\n\nYou already know what a link is!\n\nMarkup\n ````\n The [Game Boy] (en.wikipedia.org/wiki/Game_Boy) was my first video game system.\n ````\n\nOutput\n The [Game Boy] (en.wikipedia.org/wiki/Game_Boy) was my first video game system.\n\nA link consists of two parts: content and a URL.\n\nTo produce a link, simply enclose its content in square brackets or parentheses, then enclose its URL in square brackets or parentheses.\n\nYou can use mix and match either type of bracket---they’re totally interchangeable.\n\nMarkup\n ````\n - Buy [milk] (en.wikipedia.org/wiki/Milk)\n - Buy (bread) [en.wikipedia.org/wiki/Bread]\n - Buy [sugar] [en.wikipedia.org/wiki/Sugar]\n - Buy (happiness) (en.wikipedia.org/wiki/Happiness)\n ````\n\nOutput\n - Buy [milk] (en.wikipedia.org/wiki/Milk)\n - Buy (bread) [en.wikipedia.org/wiki/Bread]\n - Buy [sugar] [en.wikipedia.org/wiki/Sugar]\n - Buy (happiness) (en.wikipedia.org/wiki/Happiness)\n\nAs demonstrated above, you can omit a link’s URL scheme. [^ `http://` and `https://` are common examples of URL schemes.] If you do, Up uses `https://` for the URL scheme.\n\nIf you’re a software developer using the Up library, you can specify a different default URL scheme. To learn more, see [topic: `defaultUrlScheme`].\n\nOther settings affecting links are:\n\n- [topic: `baseForUrlsStartingWithSlash`]\n- [topic: `baseForUrlsStartingWithHashMark`]\n- [topic: `renderDangerousContent`]\n\n\nLinks with URLs containing spaces\n=================================\n\nIf your link URL contains spaces, Up assumes you *aren’t* actually trying to produce a link. So it avoids producing one!\n\nMarkup\n ````\n Warlocked is the best game for GameBoy [sic] (other than Pokémon).\n ````\n\nOutput\n Warlocked is the best game for GameBoy [sic] (other than Pokémon).\n\nIf your link URL really does contain spaces, you can make it clear that you intend to produce a link by omitting the space between your link’s content and its URL.\n\nMarkup\n ````\n I love the [music](duckduckgo.com/?q=chrono cross music) for Chrono Cross.\n ````\n\nOutput\n I love the [music](duckduckgo.com/?q=chrono cross music) for Chrono Cross.\n\nWhen you omit the space between your link’s content and its URL, Up always produces a link.\n\nThese rules also apply when [topic: linkifying].\n\n\nBare URLs\n=========\n\nAlternatively, if you include a bare URL in your document, Up will automatically produce a link for you.\n\nMarkup\n ````\n https://en.wikipedia.org/wiki/John_Carmack\n ````\n\nOutput\n https://en.wikipedia.org/wiki/John_Carmack\n\n\n=============\nInline quotes\n=============\n\nUp automatically recognizes quoted text.\n\nIf you want to quote more a few sentences, considering using [topic: blockquotes].\n\nMarkup\n ````\n "Only eat the green grapes," John said.\n ````\n\nOutput\n "Only eat the green grapes," John said.\n\nYou already know how to use quotation marks! Just keep doing what you’re doing.\n\nLike most inline writing conventions, inline quotes can be nested within themselves.\n\nMarkup\n ````\n Bob replied, "Yesterday, Harvey yelled "I’ll take the case!", but I doubt he will."\n ````\n\nOutput\n Bob replied, "Yesterday, Harvey yelled "I’ll take the case!", but I doubt he will."\n\n\n==================\nParenthetical text\n==================\n\nUp automatically recognizes parenthetical text.\n\nMarkup\n ````\n When I was ten years old, I left my home (in Pallet Town) to search for Pokémon.\n ````\n\nOutput\n When I was ten years old, I left my home (in Pallet Town) to search for Pokémon.\n\nUp understands that text enclosed within parentheses or square brackets represents supplemental content.\n\n\n==================\nExample user input\n==================\n\nUse the example user input convention to represent user input, including:\n\n- Keys the user should press\n- Buttons the user should click\n- Menu items the user should access\n\nMarkup\n ````\n Press {esc} to quit.\n ````\n\nOutput\n Press {esc} to quit.\n\nTo indicate that text represents user input, enclose the text within curly brackets.\n\nUp ignores any spaces separating the curly brackets from the content they enclose.\n\nMarkup\n ````\n Press { Start Game } when you are ready.\n ````\nOutput\n Press { Start Game } when you are ready.\n\nWithin example user input, most writing conventions are ignored. However, [topic: typographical writing conventions] are supported.\n\n\n===========\nInline code\n===========\n\nUse the inline code convention to represent a small fragment of computer code.\n\nWhen you need to represent more than a small fragment of computer code, use [topic: code blocks] instead.\n\nMarkup\n ````\n In HTML, you probably shouldn’t use the `` element.\n ````\n\nOutput\n In HTML, you probably shouldn’t use the `` element.\n\nTo produce inline code, enclose text within an equal number of backticks on either side. You can use any number of backticks---simply make sure both sides match.\n\nMarkup\n ````\n In HTML, you probably shouldn’t use the ```` element.\n ````\n\nOutput\n In HTML, you probably shouldn’t use the ```` element.\n\nWithin inline code, other writing conventions are ignored. Characters that normally have special meaning are preserved as plain text.\n\nMarkup\n ````\n In Up, surround text with `*asterisks*` to emphasize it.\n ````\n\nOutput\n In Up, surround text with `*asterisks*` to emphasize it.\n\n\nIncluding backticks in your code\n================================\n\nTo include backticks within inline code, you can precede each backtick with a backslash.\n\nMarkup\n ````\n `let output = \\`score:\\` + 5`\n ````\n\nOutput\n `let output = \\`score:\\` + 5`\n\nFor more information about the behavior of backslashes, see [topic: disabling].\n\nAlternatively, inline code can contain streaks of backticks that aren’t exactly as long as the inline code’s outer delimiters. No backslashes are necessary.\n\nIn this example, the delimiters are **1** backtick long, so the inline code can contain streaks of **2** backticks:\n\nMarkup\n ````\n `let output = ``score:`` + 5`\n ````\n\nOutput\n `let output = ``score:`` + 5`\n\nIn this example, the delimiters are **2** backticks long, so the inline code can contain "streaks" of **1** backtick:\n\nMarkup\n ````\n ``let output = `score:` + 5``\n ````\n\nOutput\n ``let output = `score:` + 5``\n\n--------------------------------------\nCode starting or ending with backticks\n--------------------------------------\n\nIf your inline code starts or ends with backticks, place a single space between the offending backticks and the outer delimiter. This single space is trimmed away.\n\nIn this example, the inline code both starts and ends with a backtick:\n\nMarkup\n ````\n `` `inline_code` ``\n ````\n\nOutput\n `` `inline_code` ``\n\nAny spaces beyond that single space are preserved---if there are multiple spaces between the delimiter and the starting/ending backticks, only one space is trimmed away.\n\nMarkup\n ````\n `` `inline_code` ``\n ````\n\nOutput\n `` `inline_code` ``\n\nFurthermore, that single space is only trimmed away when it’s necessary to separate a delimiter from backticks in your inline code. If a given "side" of inline code has any non-space characters between the delimiter and the outermost backtick, no spaces are trimmed from that side.\n\nMarkup\n ````\n `` (`inline_code`) ``\n ````\n\nOutput\n `` (`inline_code`) ``\n\n\n========\nHeadings\n========\n\nUse headings to introduce a new section in the document.\n\nMarkup\n ````\n Example heading\n ===============\n ````\n\nOutput\n Example heading\n ===============\n\nIf text is underlined, it’s treated as a heading. The underline can consist of any combination of the following characters (you can mix and match):\n\n- Hyphens: `-`\n- Number signs: `#`\n- Equal signs: `=`\n- Plus signs: `+`\n- Tildes: `~`\n- Colons: `:`\n- Asterisks: `*`\n- At signs: `@`\n\nA heading’s underline must be at least three characters long, but it does *not* need to be the same length as the text of the heading.\n\nMarkup\n ````\n Example heading with a short underline\n ===\n ````\n\nOutput\n Example heading with a short underline\n ===\n\n\nHeading levels\n==============\n\nThe first heading in a document is always a top-level heading. All subsequent headings with underlines consisting of the same characters are considered top-level.\n\nThe first heading with a different combination of underline characters is considered a second-level heading. Unsurprisingly, all subsequent headings with underlines consisting of the same characters are also considered second-level.\n\nThis process continues _ad infinitum_. Every new combination of heading underline characters introduces a new heading level. There is no limit to the number of heading levels in a document.\n\n\nHeadings with "overlines"\n=========================\n\nA heading can have an optional "overline", but its overline must consist of the same combination of characters as its underline.\n\nMarkup\n ````\n --------------------------------\n Example heading with an overline\n --------------------------------\n ````\n\nOutput\n --------------------------------\n Example heading with an overline\n --------------------------------\n\nFor the purpose of determining heading levels, a heading with an overline is always considered distinct from a heading without one, even if both headings use the same combination of underline characters.\n\nTherefore, a heading with an overline will never have the same level as a heading without an overline.\n\n\n=============\nSection links\n=============\n\nUse the section link convention to link to another section (heading) in your document.\n\nMarkup\n ````\n Up even supports [topic: overlapping]!\n ````\n\nOutput\n Up even supports [topic: overlapping]!\n\nTo link to a heading, choose a unique snippet of markup from that heading’s content line.

Section links ignore both.] Enclose that markup snippet within square brackets or parentheses, then insert `topic:` or `section:` directly inside your opening bracket.\n\nUp automatically matches your snippet to the most appropriate heading, then produces a link for you.\n\n\nMatching the most appropriate heading\n=====================================\n\nInitially, Up tries to match your section link to the first heading whose content line’s markup *exactly matches* your snippet. [^ Up totally ignores the capitalization of section links\' markup snippets, so a section link and a heading can be an "exact match" without being capitalized the same way.] If there isn’t an exact match, Up matches your section link to the first heading whose content line markup *contains* your snippet.\n\n\n=========\nFootnotes\n=========\n\nUse the footnote convention for asides or citations---anything you want to say without breaking the flow of a paragraph.\n\nFootnotes are automatically extracted into blocks for you.\n\nMarkup\n ````\n Warlocked [^ No relation to Warcraft!] is a real-time strategy game.\n ````\n\nOutput\n Warlocked [^ No relation to Warcraft!] is a real-time strategy game.\n\nTo produce a footnote, enclose its content within parentheses or square brackets.

Up supports:\n\n- Super easy [topic: tables]\n- [Topic: revealable content] (e.g. spoilers)\n- [Topic: description lists]\n- [Topic: overlapping]\n- So much more!\n\nFor software developers, Up offers a software library that converts Up markup into HTML. To learn more, please see [topic: using the Up library].\n\n\n\n===========\nWhy use Up?\n===========\n\nUp isn’t the only markup language that produces HTML. What makes it special?\n\n\nUp has a flexible, forgiving syntax\n===================================\n\nUp recognizes [topic: numbered lists] that count backwards.\n\nMarkup\n ````\n 3) Buy milk\n 2) Buy bread\n #) Buy happiness\n ````\n\nOutput\n 3) Buy milk\n 2) Buy bread\n #) Buy happiness\n\nUp usually ignores [topic: excessive delimiter characters].\n\nFor example, you don’t need to perfectly balance asterisks when stressing or emphasizing text.\n\nMarkup\n ````\n I ***love****** asterisks!\n ````\n\nOutput\n I ***love****** asterisks!\n\nUp isn’t picky about which brackets you use for [topic: links].\n\nMarkup\n ````\n - Buy [milk] (en.wikipedia.org/wiki/Milk)\n - Buy (bread) [en.wikipedia.org/wiki/Bread]\n - Buy [sugar] [en.wikipedia.org/wiki/Sugar]\n - Buy (happiness) (en.wikipedia.org/wiki/Happiness)\n ````\n\nOutput\n - Buy [milk] (en.wikipedia.org/wiki/Milk)\n - Buy (bread) [en.wikipedia.org/wiki/Bread]\n - Buy [sugar] [en.wikipedia.org/wiki/Sugar]\n - Buy (happiness) (en.wikipedia.org/wiki/Happiness)\n\nUp even supports [topic: overlapping]!\n\nMarkup\n ````\n John **enjoys ==sleeping** late== whenever he can.\n ````\n\nOutput\n John **enjoys ==sleeping** late== whenever he can.\n\n\nUp uses customizable keywords\n=============================\n\nToo many markup languages devolve into a dense soup of symbols and punctuation.\n\nWhen a keyword would provide more clarity than a symbol, Up takes advantage of that! Several writing conventions, including [topic: tables] and [topic: revealable content], incorporate keywords.\n\nIf you’re a software developer using the Up library, you can provide multiple custom variations for each keyword. To learn more, please see [topic: customizing keywords].\n\n\nUp produces fully accessible HTML\n=================================\n\nFrom the table of contents to the last movie-ruining spoiler, Up always produces fully accessible HTML. That means everyone can enjoy the documents you create, regardless of their physical ability.\n\n\n\n=================\nWhy *not* use Up?\n=================\n\nYou want a rich ecosystem of tools\n==================================\n\nThere is only one [software library for Up] (npmjs.com/package/@xcvz/up), written and maintained by only one [person] (github.com/start). In contrast, [other markup languages] (duckduckgo.com/?q=markdown) have countless tools and plugins.\n\n\nYou need speed\n==============\n\nUp is not terribly slow, but it’s not terribly fast, either---at least not yet! If you need instant, real-time parsing and rendering of large documents, Up isn’t the best markup language for you.\n\n\n\n###################\nWriting conventions\n###################\n\nDon’t get lost! The following terms are occasionally used throughout this section.\n\nWriting convention\n Any special annotation or formatting recognized by Up.\n\nInline writing convention\n Any writing convention that can be used within paragraphs. This includes [topic: emphasis] and [topic: highlighting].\n\nOutline writing convention\n Any non-inline writing convention. This includes [topic: paragraphs] and [topic: tables].\n\n\n==========\nParagraphs\n==========\n\nParagraphs are the simplest writing convention in Up.\n\nMarkup\n ````\n Unlike regular dental floss, floss picks are easy to use even if you’re not a trained dental hygienist.\n\n Floss picks are sold in stylish, resealable plastic bags. Buy some today!\n ````\n\nOutput\n Unlike regular dental floss, floss picks are easy to use even if you’re not a trained dental hygienist.\n\n Floss picks are sold in stylish, resealable plastic bags. Buy some today!\n\nTo produce a paragraph, write a line of text. That’s all there is to it!\n\nTypically, paragraphs are separated by one or two blank lines. Three or more blank lines between paragraphs indicate a meaningful change of subject. To learn more, see [topic: thematic breaks].\n\nIn contrast, *consecutive* non-blank lines produce [topic: line blocks], not consecutive paragraphs.\n\n\n===========\nLine blocks\n===========\n\nUse the line block convention for addresses, lyrics, or anything consisting of *lines* instead of actual [topic: paragraphs].\n\nMarkup\n ````\n Have you read my new poem?\n\n Roses are red\n Violets *aren’t* blue\n Lyrics have lines\n And addresses do, too\n\n Poetry is just too easy.\n ````\n\nOutput\n Have you read my new poem?\n\n Roses are red\n Violets *aren’t* blue\n Lyrics have lines\n And addresses do, too\n\n Poetry is just too easy.\n\nConsecutive non-blank lines produce a line block, unless those lines represent another writing convention, like [topic: numbered lists].\n\n\n========\nEmphasis\n========\n\nUse the emphasis convention to emphasize a word or phrase.\n\nIf the reader should pronounce a word or phrase differently (e.g. to indicate contrast or sarcasm), consider emphasizing it.\n\nMarkup\n ````\n Only eat the *green* grapes. The red grapes are for Pikachu.\n ````\n\nOutput\n Only eat the *green* grapes. The red grapes are for Pikachu.\n\nTo emphasize text, enclose it within single asterisks.\n\nLike most inline writing conventions, emphasis can be nested within itself.\n\nMarkup\n ````\n John really, *really, *really** hates Red Delicious apples.\n ````\n\nOutput\n John really, *really, *really** hates Red Delicious apples.\n\n\n======\nStress\n======\n\nUse the stress convention to indicate a word or phrase is particularly important.\n\nIf the reader should raise their voice while reading a word or phrase, consider stressing it.\n\nMarkup\n ````\n Do **not** step on the dinosaur!\n ````\n\nOutput\n Do **not** step on the dinosaur!\n\nTo stress text, enclose it within double asterisks.\n\nLike most inline writing conventions, stress can be nested within itself.\n\nMarkup\n ````\n John really, **really, **really**** hates Red Delicious apples.\n ````\n\nOutput\n John really, **really, **really**** hates Red Delicious apples.\n\n\n=======\nItalics\n=======\n\nUse the italic convention to stylistically offset a word or phrase from the surrounding text *without* conveying emphasis. The titles of books and movies should probably be italicized.\n\nIf you want to emphasize text, see [topic: emphasis].\n\nMarkup\n ````\n My favorite video game is _Chrono Cross_.\n ````\n\nOutput\n My favorite video game is _Chrono Cross_.\n\nTo italicize text, enclose it within single underscores.\n\nLike most inline writing conventions, italicized text can be nested within itself.\n\nMarkup\n ````\n My favorite show is _Real Recipes _Redux_: Super Suppers_.\n ````\n\nOutput\n My favorite show is _Real Recipes _Redux_: Super Suppers_.\n\n\n====\nBold\n====\n\nTypically, people use bold text to convey extra importance---but that’s what the [topic: stress] convention is for!\n\nTo make a word or phrase bold *without* conveying any extra importance, use the plain old bold convention.\n\nMarkup\n ````\n Has anyone actually used __KABOOM__ cleaning products?\n ````\n\nOutput\n Has anyone actually used __KABOOM__ cleaning products?\n\nTo make text bold, enclose it within double underscores.\n\nLike most inline writing conventions, bold text can be nested within itself.\n\nMarkup\n ````\n We’ve all seen the ads.\n\n __No hard scrubbing! __KABOOM__... and the stains are gone!__\n ````\n\nOutput\n We’ve all seen the ads.\n\n __No hard scrubbing! __KABOOM__... and the stains are gone!__\n\n\n============\nHighlighting\n============\n\nTo draw attention to text *without* strictly altering its semantics, use the highlighting convention.\n\n(Generally, highlighting shouldn’t be used to emphasize or stress text. If that’s your purpose, see [topic: emphasis] or [topic: stress].)\n\nMarkup\n ````\n Our cupcakes are organic, ==gluten-free==, and made using only the most expensive ingredients.\n ````\n\nOutput\n Our cupcakes are organic, ==gluten-free==, and made using only the most expensive ingredients.\n\nTo highlight text, enclose it within two or more equal signs.\n\nLike most inline writing conventions, highlighting can be nested within itself.\n\nMarkup\n ````\n Our cupcakes are ==organic, ==gluten-free==, vegan==, and made using only the most expensive ingredients.\n ````\n\nOutput\n Our cupcakes are ==organic, ==gluten-free==, vegan==, and made using only the most expensive ingredients.\n\n\n=====\nLinks\n=====\n\nYou already know what a link is!\n\nMarkup\n ````\n The [Game Boy] (en.wikipedia.org/wiki/Game_Boy) was my first video game system.\n ````\n\nOutput\n The [Game Boy] (en.wikipedia.org/wiki/Game_Boy) was my first video game system.\n\nA link consists of two parts: content and a URL.\n\nTo produce a link, simply enclose its content in square brackets or parentheses, then enclose its URL in square brackets or parentheses.\n\nYou can use mix and match either type of bracket---they’re totally interchangeable.\n\nMarkup\n ````\n - Buy [milk] (en.wikipedia.org/wiki/Milk)\n - Buy (bread) [en.wikipedia.org/wiki/Bread]\n - Buy [sugar] [en.wikipedia.org/wiki/Sugar]\n - Buy (happiness) (en.wikipedia.org/wiki/Happiness)\n ````\n\nOutput\n - Buy [milk] (en.wikipedia.org/wiki/Milk)\n - Buy (bread) [en.wikipedia.org/wiki/Bread]\n - Buy [sugar] [en.wikipedia.org/wiki/Sugar]\n - Buy (happiness) (en.wikipedia.org/wiki/Happiness)\n\nAs demonstrated above, you can omit a link’s URL scheme. [^ `http://` and `https://` are common examples of URL schemes.] If you do, Up uses `https://` for the URL scheme.\n\nIf you’re a software developer using the Up library, you can specify a different default URL scheme. To learn more, see [topic: `defaultUrlScheme`].\n\nOther settings affecting links are:\n\n- [topic: `baseForUrlsStartingWithSlash`]\n- [topic: `baseForUrlsStartingWithHashMark`]\n- [topic: `renderDangerousContent`]\n\n\nLinks with URLs containing spaces\n=================================\n\nIf your link URL contains spaces, Up assumes you *aren’t* actually trying to produce a link. So it avoids producing one!\n\nMarkup\n ````\n Warlocked is the best game for GameBoy [sic] (other than Pokémon).\n ````\n\nOutput\n Warlocked is the best game for GameBoy [sic] (other than Pokémon).\n\nIf your link URL really does contain spaces, you can make it clear that you intend to produce a link by omitting the space between your link’s content and its URL.\n\nMarkup\n ````\n I love the [music](duckduckgo.com/?q=chrono cross music) for Chrono Cross.\n ````\n\nOutput\n I love the [music](duckduckgo.com/?q=chrono cross music) for Chrono Cross.\n\nWhen you omit the space between your link’s content and its URL, Up always produces a link.\n\nThese rules also apply when [topic: linkifying].\n\n\nBare URLs\n=========\n\nAlternatively, if you include a bare URL in your document, Up will automatically produce a link for you.\n\nMarkup\n ````\n https://en.wikipedia.org/wiki/John_Carmack\n ````\n\nOutput\n https://en.wikipedia.org/wiki/John_Carmack\n\n\n=============\nInline quotes\n=============\n\nUp automatically recognizes quoted text.\n\nIf you want to quote more a few sentences, considering using [topic: blockquotes].\n\nMarkup\n ````\n "Only eat the green grapes," John said.\n ````\n\nOutput\n "Only eat the green grapes," John said.\n\nYou already know how to use quotation marks! Just keep doing what you’re doing.\n\nLike most inline writing conventions, inline quotes can be nested within themselves.\n\nMarkup\n ````\n Bob replied, "Yesterday, Harvey yelled "I’ll take the case!", but I doubt he will."\n ````\n\nOutput\n Bob replied, "Yesterday, Harvey yelled "I’ll take the case!", but I doubt he will."\n\n\n==================\nParenthetical text\n==================\n\nUp automatically recognizes parenthetical text.\n\nMarkup\n ````\n When I was ten years old, I left my home (in Pallet Town) to search for Pokémon.\n ````\n\nOutput\n When I was ten years old, I left my home (in Pallet Town) to search for Pokémon.\n\nUp understands that text enclosed within parentheses or square brackets represents supplemental content.\n\n\n==================\nExample user input\n==================\n\nUse the example user input convention to represent user input, including:\n\n- Keys the user should press\n- Buttons the user should click\n- Menu items the user should access\n\nMarkup\n ````\n Press {esc} to quit.\n ````\n\nOutput\n Press {esc} to quit.\n\nTo indicate that text represents user input, enclose the text within curly brackets.\n\nUp ignores any spaces separating the curly brackets from the content they enclose.\n\nMarkup\n ````\n Press { Start Game } when you are ready.\n ````\nOutput\n Press { Start Game } when you are ready.\n\nWithin example user input, most writing conventions are ignored. However, [topic: typographical writing conventions] are supported.\n\n\n===========\nInline code\n===========\n\nUse the inline code convention to represent a small fragment of computer code.\n\nWhen you need to represent more than a small fragment of computer code, use [topic: code blocks] instead.\n\nMarkup\n ````\n In HTML, you probably shouldn’t use the `` element.\n ````\n\nOutput\n In HTML, you probably shouldn’t use the `` element.\n\nTo produce inline code, enclose text within an equal number of backticks on either side. You can use any number of backticks---simply make sure both sides match.\n\nMarkup\n ````\n In HTML, you probably shouldn’t use the ```` element.\n ````\n\nOutput\n In HTML, you probably shouldn’t use the ```` element.\n\nWithin inline code, other writing conventions are ignored. Characters that normally have special meaning are preserved as plain text.\n\nMarkup\n ````\n In Up, surround text with `*asterisks*` to emphasize it.\n ````\n\nOutput\n In Up, surround text with `*asterisks*` to emphasize it.\n\n\nIncluding backticks in your code\n================================\n\nTo include backticks within inline code, you can precede each backtick with a backslash.\n\nMarkup\n ````\n `let output = \\`score:\\` + 5`\n ````\n\nOutput\n `let output = \\`score:\\` + 5`\n\nFor more information about the behavior of backslashes, see [topic: disabling].\n\nAlternatively, inline code can contain streaks of backticks that aren’t exactly as long as the inline code’s outer delimiters. No backslashes are necessary.\n\nIn this example, the delimiters are **1** backtick long, so the inline code can contain streaks of **2** backticks:\n\nMarkup\n ````\n `let output = ``score:`` + 5`\n ````\n\nOutput\n `let output = ``score:`` + 5`\n\nIn this example, the delimiters are **2** backticks long, so the inline code can contain "streaks" of **1** backtick:\n\nMarkup\n ````\n ``let output = `score:` + 5``\n ````\n\nOutput\n ``let output = `score:` + 5``\n\n--------------------------------------\nCode starting or ending with backticks\n--------------------------------------\n\nIf your inline code starts or ends with backticks, place a single space between the offending backticks and the outer delimiter.

                  Up uses customizable keywords

                  Too many markup languages devolve into a dense soup of symbols and punctuation.

                  When a keyword would provide more clarity than a symbol, Up takes advantage of that! Several writing conventions, including Tables and Revealable content, incorporate keywords.

                  If you’re a software developer using the Up library, you can provide multiple custom variations for each keyword. To learn more, please see Customizing keywords.

                  From the table of contents to the last movie-ruining spoiler, Up produces fully accessible HTML. This means folks who might struggle to view a screen or a use mouse can enjoy every document.

                  Why not use Up?

                  You want a rich ecosystem of tools

                  There is only one software library for Up, written and maintained by only one person. In contrast, other markup languages have countless tools and plugins.

                  You need speed

                  Up is not terribly slow, but it’s not terribly fast, either—at least not yet! If you need instant, real-time parsing and rendering of large documents, Up isn’t the best markup language for you.

                  Writing conventions

                  Don’t get lost! The following terms are occasionally used throughout this section.

                  Writing convention

                  Any special annotation or formatting recognized by Up.

                  Inline writing convention

                  Any writing convention that can be used within paragraphs. This includes Emphasis and Highlighting.

                  Outline writing convention

                  Any non-inline writing convention. This includes Paragraphs and Tables.

                  Paragraphs

                  Paragraphs are the simplest writing convention in Up.

                  To produce a paragraph, write a line of text. That’s all there is to it!

                  Typically, paragraphs are separated by one or two blank lines. Three or more blank lines between paragraphs indicate a meaningful change of subject. To learn more, see Thematic breaks.

                  In contrast, consecutive non-blank lines produce Line blocks, not consecutive paragraphs.

                  Line blocks

                  Use the line block convention for addresses, lyrics, or anything consisting of lines instead of actual Paragraphs.
