+### Platform/OS support
+
+These are the operating systems and their versions that the app officially supports. It might
+work on many more versions, but we don't test for those and can't guarantee the quality or
+security.
+
+| OS/Platform | Supported versions |
+|-------------|--------------------|
+| Windows     | 7, 8.1 and 10      |
+| macOS       | The three latest major releases |
+| Linux (Ubuntu)| The two newest LTS releases and the two newest non-LTS releases |
+| Linux (Fedora) | The versions that are not yet [EOL](https://fedoraproject.org/wiki/End_of_life) |
+| Linux (Debian) | The versions that are not yet [EOL](https://wiki.debian.org/DebianReleases) |
+| Android | The four latest major releases|
+| iOS         | 13 and newer       |
+
+On Linux we test using the Gnome desktop environment. The app should, and probably does work
+in other DEs, but we don't regularly test those.
