-<p>CodeIgniter uses Sphinx to generate its documentation in a variety of formats,
-using reStructuredText to handle the formatting. If you are familiar with
-Markdown or Textile, you will quickly grasp reStructuredText. The focus is
-on readability and user friendliness.
-While they can be quite technical, we always write for humans!</p>
-<p>A local table of contents should always be included, like the one below.
-It is created automatically by inserting the following:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">..</span> <span class="nx">contents</span><span class="o">::</span>

-<p>To see the rendered HTML, ePub, PDF, etc., you will need to install Sphinx
-along with the PHP domain extension for Sphinx. The underlying requirement
-is to have Python installed. Lastly, you will install the CI Lexer for
-Pygments, so that code blocks can be properly highlighted.</p>

-<p>Headings not only provide order and sections within a page, but they also
-are used to automatically build both the page and document table of contents.
-Headings are formed by using certain characters as underlines for a bit of
-text. Major headings, like page titles and section headings also use
-overlines. Other headings just use underlines, with the following hierarchy:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="c1"># with overline for page titles</span>
