Sharing data from the unnoficial Flatpak package with the upstream.

[Asghwor]

I've created a Flatpak package for Boram and submitted it to Flathub, and I'm sharing the following files with the upstream Boram project:

• com.github.kagami.boram.desktop
• com.github.kagami.boram.metainfo.xml
• icon-big-128x128
