+<h1>Basic Datatypes</h1>
+<p>This section covers the datatypes <cite>number</cite> and <cite>vector</cite> (resp. <cite>string</cite>) which are used in the index file.</p>
+<div class="section" id="number">
+<h2>Number</h2>
+<p>The index file contains non-negative integer values only. The format we use avoids fixed length
+integers by encoding the number of bytes into the integer itself. It has a bias towards numbers
+smaller than 0xFF, which are encoded into a single byte.</p>
+<blockquote>
+<p>To determine the number of bytes used, you must first count how often the byte <strong>0xFF</strong> occurs at
+the beginning of the number.
+Let <cite>n</cite> be this count (<cite>n</cite> may be 0). Then, as a rule, there will follow <cite>n+1</cite> bytes that
+contain the actual integer stored in big-endian byte order (highest byte first).</p>
+<p><em>But</em> since it would be impossible to store any number that has a leading 0xFF with this format,
+a leading 0xFF is stored as 0x00. Meaning, if a 0x00 byte follows the last 0xFF, you must
+interpret this byte as 0xFF inside the number.</p>
