				<h1>Wobbly Help Section</h1>
				<ul>
					<li>This browser is for casual reading. It only supports text documents, and only cares about any sort of layout in gemtext ones.</li>
					<li>Javascript has no notion of sockets that aren't http/https. Therefore all traffic from here goes through a web server that fetches and serves the gemini pages translated to html. Input and client certificates are not supported, because they would be unsafe under these circumstances.</li>
					<li>'Back' and 'Forward' buttons take you to cached versions of those pages. Pressing 'Go!' without typing in a new URL is a refresh.</li>
					<li>'Up' means to go one level higher in the path on the current domain. If you are on 'gemini://warmedal.se/~antenna/' and press 'Up' you will visit 'gemini://warmedal.se/'.</li>
					<li>Non-gemini links will open in a new tab in your browser as usual!</li>
