 Install using Pathogen, Vundle, Neobundle, or your favorite Vim package
 manager.
 
+Or simply copy the colorscheme file to your `~/.vim/colors` directory.
+
+## Usage
+
+Just like any other colorscheme:
+
+```vim
+:colorscheme pencil
+```
+
+## Differences
+
+Most notably, the ‘#’ heading text is shaded blue. This is to compensate
+for the lack of a visual cue found in iA Writer where the heading
+indicators are inside the left margin. Here we use color instead.
+
+## Font choices
+
+iA Writer uses a typeface called ‘Nitti Light’ by Blue Monday. ($)
+
+Free alternatives with bold and italic support include:

+* [Anonymous Pro](https://www.google.com/fonts/specimen/Anonymous+Pro)
+* [Courier Prime](http://quoteunquoteapps.com/courierprime/)
+* [Cousine](http://www.google.com/fonts/specimen/Cousine)
