+                        <p>Ground has recently added a Ground->Native compiler which allows much faster execution of Ground programs.</p>
+                        <p>However, this is quite early in development, and only supports some features:</p>
+                        <ul>
+                            <li>int data type - No other data type is currently supported.</li>
+                            <li>No functions at present</li>
+                        </ul>
+                        <p>To try the native compiler, use this command:</p>
+                        <pre class="code"><code>solstice program.sols -o program -t native --nostdlib</code></pre>
+                        <h3>Debugging</h3>
+                        <p>Solstice will create a temporary folder in your current directory which you can remove called ".(outputname)_solsbuild". In this folder is the assembly and object file generated by the compiler. If you think that there's a bug with Ground or Solstice, you can use these to find the issue.</p>
