 ## Forking/Redistributing/Custom builds policy
 
-Do whatever you want, we don't care. Just follow the license. If you have any questions about this feel free to ask in an issue.
+We don't care what you do with your fork as long as you do the following as a basic courtesy:
+- Follow the terms of the [license](LICENSE) (not just a courtesy, but also a legal responsibility)
+- Make it clear that your fork is not PolyMC and is not endorsed by or affiliated with the PolyMC project (https://polymc.org).
+- If you are distributing this fork, go through [CMakeLists.txt](CMakeLists.txt) and change PolyMC's API keys to your own or set them to empty strings (`""`) to disable them (this way the program will still compile but the functionality requiring to those keys will be disabled).
+
+If you have any questions or want any clarification on the above conditions please make an issue and ask us.
