+h2. Documenting your work
+
+We use "PhpDocumentor":http://www.phpdoc.org/ and "PHPXref":http://phpxref.sourceforge.net/ to automatically generate documentation for the source code. If you're creating new functions or variables, use "JavaDoc-style":http://java.sun.com/j2se/javadoc/writingdoccomments/ comments in your code.
+
+Also, please don't do this:
+<pre>
+// this function does blah
+function my_new_function($param) {
+  // initialize blah
+  $param2 = magic($param);
+  // check the new param to see if it's a number
+  if (is_numeric($param2)) {
+    // make a new number
+    $param3 = more_magic($param2);
+    // print out the number
+    echo $param3;
+  // done
+  }
+// done
+}
+</pre>
+
+Instead, do this:
+
+<pre>
+/**
+ * Print out a magic number.
+ * @param string $initial_string The string we're passing in.
+ */
+function print_magic_number($initial_string) {
+  if (is_numeric($number_version = magic($initial_string))) {
+    echo more_magic($param3);
+  }
