+# Themes Plugin
+
+This plugin allows you to change Oh-My-Bash themes on the go.
+
+To use it, add `themes` to the plugins array in your `.bashrc` file:
+
+```
+plugins=(... themes)
+```
+
+This is based off the [themes oh-my-zsh plugin](https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins/themes).
+
+## Usage
+
+`theme <theme_name>` - Changes the theme to specified theme.
+
+`theme ` - Changes the theme to some random theme.
+
+`lstheme ` - Lists installed themes.
