If you have any questions or want any clarification on the above conditions please make an issue and ask us. If you are just building Prism Launcher for your distribution, please make sure to set the `Launcher_BUILD_PLATFORM` to a slug representing your distribution. Examples are `archlinux`, `fedora` and `nixpkgs`. Note 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 (`""`). ## License [](LICENSE) All launcher code is available under the GPL-3.0-only license.
