 # Contribution Guidelines
 
+The Awesome Langchain curates content and projects using or supporting Langchain ecosystem. The contribution needs to be open source. The list is curated in a way that only the best content is listed. This means that not all content will be listed. The content that is listed should be of high quality and have a clear added value. The project needs to be active and online for at least 1 week.
+
+We do not list content that is:
+
+- not in English.
+- not related to Langchain.
+- not maintained anymore.
+- not online anymore.
+- not open source.
+- not adding value to existing content.
+
+We do not aim to list all Langchain supported platforms already listed in the Langchain documention, but we may list articles and examples demonstrating their usage.
