+
+Oh-My-Posh Theme
+================
+
+The oh-my-posh ״theme״ is really a plug to a whole other system
+of managing your prompt. To use it please start here:
+`Oh-My-Posh homepage <https://ohmyposh.dev/>`_
+
+It is beyond the scope of bash-it to install and manage oh-my-posh,
+this theme is here just to make sure your OMP setup doesn't clash
+with other bash-it themes. Once installed, OMP will load a default
+OMP theme (powerlevel10k_rainbow), which you can then
+customize or override.
+
+Note: Nerd Fonts are highly recommended, as most of the themes are graphic candies.
