           <h2>Initialise Plugin</h2>
           <p>Fresh installations and users who have just upgraded will need to initialise Formidable Pro PDF Extended to ensure it works correctly.</p>
           
           <p>Initialisation does a number of important things, including:</p>
           
           <ol>
           		<li><strong>Fresh Installation</strong>: Copies all the required template and configuration files to a folder called FORMIDABLE_PDF_TEMPLATES in your active theme's directory.<br />
                	<strong>Upgrading</strong>: Copies the latest default templates and template.css file to the FORMIDABLE_PDF_TEMPLATES folder. <strong>If you modified these files please back them up before re-initialising as they will be removed</strong>.
                </li>
           		<li>Unzips the mPDF package</li>
           		<li>Installs any fonts found in the FORMIDABLE_PDF_TEMPLATES/fonts/ folder</li>                
           </ol>
