+#### Emoji support
+
+Emojis are supported since version `0.0.12`, and it needs to be explicitly enabled, as these add a little parsing overhead via the [emojis](https://hackage.haskell.org/package/emojis) package.
+
+The following `dconf` input.
+
+```ini
+[ org/gnome/Characters ]
+recent-characters=['💡']
+some-other-character=['🤓']
+```
+
+Can be parsed as follows.
+
+```console 
+$ dconf2nix -i data/emoji.settings -o output/emoji.nix --emoji
+```
+
+Failing to pass the `--emoji` flag will result in a timeout error.

 ### Supported types
 
 For now, only types supported by Home Manager as specified [here](https://github.com/rycee/home-manager/blob/master/modules/lib/gvariant.nix) are supported. If there's enough interest, we might be able to work on supporting the [full specification](https://developer.gnome.org/glib/stable/gvariant-text.html).

 ### Installation
 
-The simplest way is to install it via `nix-env`.
+`dconf2nix` is available on [nixpkgs](https://github.com/NixOS/nixpkgs) and can be installed as any other package. It can also be used without installing. For example, with flakes.
 
-```shell
-nix-env -i dconf2nix
+```console 
+$ nix run nixpkgs#dconf2nix -- --version
