+## Usage
+
+#### Colorschemes?
+
+Colorschemes are the way to style your Vim. Vim consists of many components and
+each of those can be customized with different colors for the foreground,
+background and a few other attributes like bold text etc. They can be set like
+this:
+```viml
+:highlight Normal ctermbg=1 guibg=red
+```
+This would paint the background of the editor red. See `:h :highlight` for more
+information.
+
+So, colorschemes are mostly a collection of `:highlight` commands.
+
+Actually, most colorschemes are really 2 colorschemes! The example above sets
+colors via `ctermbg` and `guibg`. The former definition will only be used if Vim
+was started in a terminal emulator, e.g. xterm. The latter will be used in
+graphical environements like gVim.
+
+If you ever happen to use a certain colorscheme in Vim running in a terminal
+emulator and the colors don't look like the colors in the screenshot at all,
+chances are that the colorscheme only defined colors for the GUI.
+
+Here's a list of commonly used colorschemes:

+I use gruvbox for the GUI and [janah](https://github.com/mhinz/vim-janah) for
+the terminal.
