+### Theme
 
 I use [catppuccin](https://github.com/catppuccin/catppuccin) as my theme
 (the mocha variant). I love the soothing pastel colors. The GTK theme
 and the Qt5 theme are also configured to be used with supported
 applications.
 
-## Shell
+### Shell
 
 I use [fish](https://github.com/fish-shell/fish-shell) as my interactive shell, but I still keep [bash](https://www.gnu.org/software/bash/) as my non-interactive shell for compatibility purposes, as some pieces of software that I use require the user to have a POSIX compliant shell. This is why I have a bash module, where I setup everything that I want to have non-interactively and interactively and if running interactively, have it start a fish session.
