+        Thanks for your interest in 🦜️🔗 LangChain!
+
+        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, write documentation or reviewing pull requests.
+
+        By asking questions in a structured way (following this) it will be much easier to help you.
+
+        And there's a high chance that you will find the solution along the way and you won't even have to submit it and wait for an answer. 😎
+
+        As there are too many questions, 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. 🤓
