 `docker-entrypoint.sh` script does on-the-fly patching by means of manipulating dynamic linker to workaround read-only mount of Nvidia runtime. Finally it passes original docker command to shell, like if entrypoint was not restricted by `ENTRYPOINT` directive. So `docker run --runtime=nvidia -it mycontainer echo 123` will print `123`. Also it can be just invoked from your entrypoint script, if you have any.
 
+## Flatpak support
+
+If you use a Flatpak app that uses NVENC/NvFBC (e.g. OBS Studio, Kdenlive), it's recommended that you patch the NVIDIA drivers for Flatpak as well. To do so, just pass the `-f` parameter to either `patch.sh` or `patch-fbc.sh`, like so:
+
+```bash
+bash ./patch.sh -f
+bash ./patch-fbc.sh -f
+```
+
+In case something goes wrong, you can restore the original Flatpak drivers by adding the `-r` paramater:
+
+```
+bash ./patch.sh -f -r
+bash ./patch-fbc.sh -f -r
+```
