 For using with Nixpkgs, add `./overlay.nix` or `nixpkgs-gnome-mobile.overlays.default` to your Nixpkgs overlays. For using with NixOS, add `./module.nix` to your `imports` in `configuration.nix`, or `nixpkgs-gnome-mobile.nixosModules.gnome-mobile` to your `modules` in `nixpkgs.lib.nixosSystem`.

+## FAQ
+
+### Do input methods work?
+
+Yes, only IBus works. You have to be careful not to set the `*_IM_MODULE` env vars (done in `./module.nix`), or the keyboard won't pop up. Example NixOS configuration:
+
+```nix
+i18n.inputMethod.enabled = "ibus";
+i18n.inputMethod.ibus.engines = with pkgs.ibus-engines; [ libpinyin anthy ];
+```
+
+Add input methods in Settings > Keyboard, or with the following command:
+
+```shellsession
+$ dconf write /org/gnome/desktop/input-sources/sources "[('xkb', 'us'), ('ibus', 'libpinyin'), ('ibus', 'anthy')]"
+```
+
+For the Japanese IME anthy, you may also want to change the input mode from Latin to Kana:
+
+```shellsession
+$ dconf write /org/freedesktop/ibus/engine/anthy/common/input-mode 0 # Hiragana
+```

 The Wayland compositor can be started directly from the Linux console. The log is actually verbose enough to identify problems, but for unknown reasons you may have to redirect the stderr to see it:
