+If you have a setup for your project with a bundler (like Vite, Rollup, or Webpack), it is best to use the default ES import:
+
+```ts
+// for use in a React, Vue, or Angular project
+import { JSONEditor } from 'vanilla-jsoneditor'
+```
+
+If you want to use the library straight in the browser, use the provided standalone ES bundle:
+
+```ts
+// for use directly in the browser
+import { JSONEditor } from 'vanilla-jsoneditor/standalone.js'
+```
+
+The standalone bundle contains all dependencies of `vanilla-jsoneditor`, for example `lodash-es` and `Ajv`. If you use some of these dependencies in your project too, it means that they will be bundled twice in your web application, leading to a needlessly large application size. In general, it is preferable to use the default `import { JSONEditor } from 'vanilla-jsoneditor'` so dependencies can be reused.
