Made text wordpress-friendly and small edits
Made text wordpress-friendly and small edits

To make the text easily transferrable to Wordpress, I:

- Removed the specialized syntax highlighting
- Started at H1 (#). This creates a table of contents of all H1 headers along the left hand side of the Wordpress page.
- Changed the markdown tables to HTML
- Removed the "contributing" section, since it pointed to a private repository.
