A framework and GUI to construct a single Bethesda game patch from many patcher sources. Designed to allow any program to work as a patcher as long as it conforms to the CLI API.
If you're looking to install, we have a wiki page with the details.
Also be sure to head over to Discord and ask any and all questions you may have!
While Synthesis supports any external program as a patcher, it heavily facilitates creating and running Mutagen-based patchers. Take a look at the Development side of the wiki, the Mutagen documentation, or some example patchers.
