 # Emoji font
 `Noto Color Emoji` is the default emoji font and is required by default. 
 The default can be changed in `~/.config/cosmic/dev.dominiccgeh.CosmicAppletEmojiSelector/v1/font_family`.
-A font which supports Unicode 15.1 is generally recommended.

+# Copying emojis
+To copy emojis, `data_control` has to be enabled. This can be done in `/etc/cosmic-comp/config.ron`. 
+Note this grants windowless applications access to your clipboard. 
+In case this does not meet your security requirements, you can enter the unicode code points manually.
+To do so, enable `show_tooltip` and `show_unicode` in `~/.config/cosmic/dev.dominiccgeh.CosmicAppletEmojiSelector/v1/show_tooltip`
+`~/.config/cosmic/dev.dominiccgeh.CosmicAppletEmojiSelector/v1/show_unicode` respectivly.
+Now press `Shift` + `Ctrl` + `U`, then enter the first code, e.g. `1F1E9`, finally press `Shift` + `Ctrl` to enter the code point. 
+After that repeat this step for the remaining code points, in this example `1F1EA` and it will output 🇩🇪.
