Installation

• All downloads and instructions for Prism Launcher can be found on our Website.

Prebuilt Development builds are provided for Linux, Windows and macOS.

For Arch, Debian, Fedora, OpenSUSE (Tumbleweed) and Gentoo, respectively, you can use these packages for the latest development versions:

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 (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 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 you are accepting the following terms and conditions:

• Microsoft Identity Platform Terms of Use
• CurseForge 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 file by setting them to an empty string ("").
