+# Frequently Asked Questions
+
+## Window Names
+
+By default, window names are the pane title, and the pane title is
+set by the shell running in each pane. Oh My ZSH does this [automatically](https://github.com/ohmyzsh/ohmyzsh/wiki/Settings#automatic-title),
+as does [fish](https://fishshell.com/docs/current/cmds/fish_title.html).
+
+The format string used can be changed by setting the following options:
+
+```bash
+set -g @catppuccin_window_text "#W"
+set -g @catppuccin_window_current_text "#W"
+```
+
+The window title is `#W`, the current path is `#{b:pane_current_path}`. A huge
+amount of customisation is possible, and is explained in depth
+in the "[tmux man page](https://man7.org/linux/man-pages/man1/tmux.1.html#FORMATS)".
+
+## Symbols are not displaying
+
+Make sure you have installed a [Nerd Font](https://www.nerdfonts.com/),
+and that your terminal is set to use that font.
+
+## My options are not being applied
+
+Go through these steps:
+
+1. Completely kill tmux and restart (`killall tmux`).
+1. Ensure every `@catppuccin.*` option is being set _before_
+   the plugin is loaded. Loading occurs where you have `run` in your config file.
+1. Double check for typos. There are two "c"s and two "p"s in "catppuccin".
+1. Do not use `-o` to set options that begin with `@`. The `-o` flag means that
+   the option will not be set if it has already been set. You do not need this
+   in your config file.
+1. Double check that any option that does _not_ start with `@` is set after the
+   plugin is loaded.
