Looks good overall, just a few issues to sort out before we can include it.
I would consider using a different summary, this is Linux we don't really care that's it's available for MacOS and Windows.
To fix errors at the end of the build such as Fatal: Unknown symbol: libXcursor.so.1 you need the following builddeps:
- pkgconfig(alsa) - pkgconfig(fontconfig) - pkgconfig(gconf-2.0) - pkgconfig(gtk+-3.0) - pkgconfig(xscrnsaver) - cups-devel
yarn depends on nodejs so adding nodejs as a builddep is not necessary.
Very nitpicky but the quotations are not necessary
