+### Usage without an autoloader
+
+If you cannot use class autoloading, you can still use `include` or `require` 
+to access the parser. To load the `\Michelf\Markdown` parser, do it this way:
+
+	require_once 'Michelf/Markdown.inc.php';
+
+Or, if you need the `\Michelf\MarkdownExtra` parser:
+
+	require_once 'Michelf/MarkdownExtra.inc.php';
+
+While the plain `.php` files depend on autoloading to work correctly, using the
+`.inc.php` files instead will eagerly load the dependencies that would be 
+loaded on demand if you were using autoloading.
