+µ-Player
+========
+
+Minimalistic video player using GTK4 and GStreamer. The main purpose is to make
+playing hw accelerated videos with hantro and OpenGL simple.
+
+It supports:
+
+- Inhibiting suspend/idle when playing video
+- Stopping video playback on (i.e. power button toggled) screen lock
+- Registering as default video player in GNOME control center
+
+![Playing video in landscape fullscreen mode](screenshots/landscape-fullscreen.png)
+
+Building
+========
+
+Most distribution don't ship recent enough GTK4 and gstreamer atm so it's simplest
+to build and install as a flatpak via
+
+    flatpak-builder --force-clean  --install --user _build/ org.sigxcpu.Livi.json
