+### How do I enable audio?
+
+  Audio is disabled by default. To stream it to the browser, add the following environment variable:
+
+  ```yaml
+  environment:
+    AUDIO: "Y"
+  ```
+
+  Then enable **Audio** under **Settings → Advanced** in the web viewer. The stream is only active while this option is enabled, so it uses no extra bandwidth otherwise.
+
+### How do I share files with the host?
+
+  To share files with the host, add the following volume to your compose file:
+
+  ```yaml
+  volumes:
+    - ./example:/shared
+  ```
+
+  Then start macOS and execute the following command:
+  
+  ```shell
+  sudo -S mount_9p shared
+  ```
+
+  In Finder’s menu bar, click on “Go – Computer” to access this shared folder, it will show the contents of `./example`.
