    General guidance from repository metadata, not legal advice. How we score

    From the README

    Proton is a tool for use with the Steam client which allows games which are exclusive to Windows to run on the Linux operating system. It uses Wine to facilitate this.

    Most users should use Proton provided by the Steam Client itself. See this Steam Community post for more details.

    The source code is provided to enable advanced users the ability to alter Proton. For example, some users may wish to use a different version of Wine with a particular title.

    The changelog is available on our wiki.

    Acquire Proton's source by cloning https://github.com/ValveSoftware/Proton and checking out the branch you desire.

    You can clone the latest Proton to your system with this command:

    Be sure to update submodules when switching between branches:

    If you want to change any subcomponent, now is the time to do so. For example, if you wish to make changes to Wine, you would apply them to the wine/ directory.

    Most of Proton builds inside the Proton SDK container with very few dependencies on the host side.
