+      <h2>Example Usage</h2>
+      <p>ttyd starts web server at port <code>7681</code> by default, you can use the <code>-p</code> option to change it, the <code>command</code> will be started with <code>arguments</code> as options. For example, run:</p>
+      <pre><code class="language-bash">ttyd -p 8080 bash -x</code></pre>
+      <p>Then open <a href="http://localhost:8080">http://localhost:8080</a> with a broswer, you will get a bash shell with debug mode enabled.</p>
+      <p><strong>More Examples:</strong></p>
+      <ul>
+        <li>If you want to login with your system accounts on the web broswer, run <code>ttyd login</code>.</li>
+        <li>You can even run a none shell command like vim, try: <code>ttyd vim</code>, the web broswer will show you a vim editor.</li>
+        <li>Sharing single process with multiple clients: <code>ttyd tmux new -A -s ttyd vim</code>, run <code>tmux new -A -s ttyd</code> to connect to the tmux session from terminal.</li>
+      </ul>
+      <h2>Docker and ttyd</h2>
+      <p>Docker containers are jailed environments which are more secure, this is useful for protecting the host system, you may use ttyd with docker like this:</p>
+      <ul>
+        <li>Sharing single docker container with multiple clients: <code>docker run -it --rm -p 7681:7681 tsl0922/ttyd</code>.</li>
+        <li>Creating new docker container for each client: <code>ttyd docker run -it --rm ubuntu</code>.</li>
+      </ul>
