+### Making `undercurls` work properly in **Tmux**
+
+To have undercurls show up and in color, add the following to your **Tmux** config file:
+
+```sh
+# Undercurl
+set -g default-terminal "${TERM}"
+set -as terminal-overrides ',*:Smulx=\E[4::%p1%dm'  # undercurl support
+set -as terminal-overrides ',*:Setulc=\E[58::2::%p1%{65536}%/%d::%p1%{256}%/%{255}%&%d::%p1%{255}%&%d%;m'  # underscore colours - needs tmux-3.0
+```
+
 ## 🍭 Extras
 
 Extra color configs for **Kitty**, **Alacritty**, **Fish** and **iTerm** can be found in [extras](extras/). To use them, refer to their respective documentation.
