 ## Contributing
 
-Contributions are most welcome! The parser itself is pretty stupidly naive and I wouldn't be surprised if it breaks with edge cases.
+Contributions are welcome, but with some caveats.
 
-*code changes without tests will not be accepted*
+This library has been declared feature complete (see [#182](https://github.com/joho/godotenv/issues/182) for background) and will not be accepting issues or pull requests adding new functionality or breaking the library API.
+
+Contributions would be gladly accepted that:
+
+* bring this library's parsing into closer compatibility with the mainline dotenv implementations, in particular [Ruby's dotenv](https://github.com/bkeepers/dotenv) and [Node.js' dotenv](https://github.com/motdotla/dotenv)
+* keep the library up to date with the go ecosystem (ie CI bumps, documentation changes, changes in the core libraries)
+* bug fixes for use cases that pertain to the library's purpose of easing development of codebases deployed into twelve factor environments
+
+*code changes without tests and references to peer dotenv implementations will not be accepted*
