+Injecting HTML in the game
+==========================
+
+Bitburner uses React and Material-UI to render everything. Modifying the UI is possible but
+not officially supported.
+
+To automatically enter commands in the terminal (only works if looking at the terminal):
+
+.. code-block:: javascript
+
+    // Acquire a reference to the terminal text field
+    const terminalInput = document.getElementById("terminal-input");
+
+    // Set the value to the command you want to run.
+    terminalInput.value="home;connect n00dles;home;connect n00dles;home;";
+
+    // Get a reference to the React event handler.
+    const handler = Object.keys(terminalInput)[1];
+
+    // Perform an onChange event to set some internal values.
+    terminalInput[handler].onChange({target:terminalInput});
+
+    // Simulate an enter press
+    terminalInput[handler].onKeyDown({keyCode:13,preventDefault:()=>null});
+
+
+To add lines to the terminal (only works if looking at the terminal):
+
+.. code-block:: javascript
+
+    // Acquire a reference to the terminal list of lines.
+    const list = document.getElementById("generic-react-container").querySelector("ul");
+
+    // Inject some HTML.
+    list.insertAdjacentHTML('beforeend',`<li><p color=lime>whatever custom html</p></li>`)
