+        Thanks for your interest in LangChain.js 🦜️🔗!
+
+        Please follow these instructions, fill every question, and do every step. 🙏
+
+        We're asking for this because answering questions and solving problems in GitHub takes a lot of time --
+        this is time that we cannot spend on adding new features, fixing bugs, writing documentation or reviewing pull requests.
+
+        By asking questions in a structured way (following this) it will be much easier for us to help you.
+
+        There's a high chance that by following this process, you'll find the solution on your own, eliminating the need to submit a question and wait for an answer. 😎
+
+        As there are many questions submitted every day, we will **DISCARD** and close the incomplete ones. 
+
+        That will allow us (and others) to focus on helping people like you that follow the whole process. 🤓
