You can build Umbra yourself but using the build script at https://github.com/openconstruct/user-agent-desktop
Or downod binaries for Linux/WIn at https://github.com/openconstruct/umbra/releases
I assume your disability is related to grammar, since there are a lot of errors in your Readme, or you might just not be that good with English yet. Whatever the case might be, it would look more trustworthy and professional if you would fix those.
