+this theme:
 
-You just need to install the theme and set `POWERLEVEL9K_MODE='compatible'`
-to join the experience. If you want to customize your experience even further
-read the chapter about "[fonts](#fonts)" or about "[segment customization](#segment-customization)".

+
+#### Install Powerline Fonts for Normal Configuration
+
+You can find the [installation instructions for Powerline Fonts here]
+(https://powerline.readthedocs.org/en/latest/installation/linux.html#fonts-installation).
+You can also find the raw font files [in this Github
+repository](https://github.com/powerline/fonts) if you want to manually install
+them for your OS.
+
+After you have installed Powerline fonts, make the default font in your terminal
+emulator the Powerline font you want to use.
+
+This is the default mode for `Powerlevel9k`, and no further configuration is
+necessary.
+
+#### Alternative Configuration: Über
+
+Alternatively, you can install [Awesome Powerline
+Fonts](https://github.com/gabrielelana/awesome-terminal-fonts), which provide
+a number of additional glyphs.
+
+You then need to indicate that you wish to use the additional glyphs by defining
+the following in your `~/.zshrc`:
+
+    POWERLEVEL9K_MODE='awesome-patched'
+
+If you choose to make use of this, your prompt will look something like this:

+
+Note that if you prefer flat segment transitions, you can use the following with
+`Awesome Powerline Fonts` installed:
+
+    POWERLEVEL9K_MODE='flat'
+
+Which looks like this:

+
+#### Alternative Configuration: Bare Bones
+
+This option is best if you prefer not to install additional fonts. This option
+will work out-of-the-box if your your terminal font supports the segment
+separator characters `\uE0B0` (left segment separator) and `\uE0B2` (right
+segment separator).
+
+All you need to do to in this case is install the `Powerlevel9k` theme itself,
+as explained above, and then define the following in your `~/.zshrc`:
+
+    POWERLEVEL9K_MODE='compatible'
+
+Note that depending on your terminal font, this may still not render
+appropriately. This configuration should be used as a back-up.
