Fotorelacjonusz is free software distributed under the terms of the GNU General Public License version 3 or (at your option) any later version.
On GNU+Linux, you may want to download a DEB or RPM package, and then install it with your system package manager. Alternatively, you may download the TAR.GZ archive and unpack it to a preferred location.
On macOS, unpack the downloaded ZIP file. It contains an application bundle, which you may move to Applications directory if you want to. Make sure that your system settings allow for running software from outside of App Store.
On Windows, unpack the downloaded ZIP file. The executable is inside extracted directory. Don’t move your files around, or it won’t work. There is no nice installer (yet), unfortunately, but help is welcome.
