+## Building
+
+If you want to build Prism Launcher yourself, check the [Build Instructions](https://prismlauncher.org/wiki/development/build-instructions/).
+
+## Translations
+
+The translation effort for PrismLauncher is hosted on [Weblate](https://hosted.weblate.org/projects/prismlauncher/launcher/) and information about translating Prism Launcher is available at <https://github.com/PrismLauncher/Translations>
+
+## Forking/Redistributing/Custom builds policy
+
+We don't care what you do with your fork/custom build as long as you follow the terms of the [license](LICENSE) (this is a legal responsibility), and if you made code changes rather than just packaging a custom build, please do the following as a basic courtesy:
+
+- Make it clear that your fork is not PrismLauncher and is not endorsed by or affiliated with the PrismLauncher project (<https://prismlauncher.org>).
+- Go through [CMakeLists.txt](CMakeLists.txt) and change PrismLauncher'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 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.
+
+Be aware that if you build this software without removing the provided API keys in [CMakeLists.txt](CMakeLists.txt) you are accepting the following terms and conditions:
+
+- [Microsoft Identity Platform Terms of Use](https://docs.microsoft.com/en-us/legal/microsoft-identity-platform/terms-of-use)
+- [CurseForge 3rd Party API Terms and Conditions](https://support.curseforge.com/en/support/solutions/articles/9000207405-curse-forge-3rd-party-api-terms-and-conditions)
+
+If you do not agree with these terms and conditions, then remove the associated API keys from the [CMakeLists.txt](CMakeLists.txt) file by setting them to an empty string (`""`).
