+## Install the Plugin
+
+- In the UNRAID webGUI, go to the **Docker** tab.
+- In the search bar, search for `homepage`.
+- Click on **Install**.
+- Change the parameters to your liking.
+  - Click on **APPLY**.
+
+## Run the Container
+
+- While the container is running, open the WebUI.
+  - Opening the page will generate the configuration files.
+
+You may need to set the permissions of the folders to be able to edit the files.
+

+
+## Some Other Notes
+
+- To use the [Docker integration](https://github.com/benphelps/homepage/wiki/Docker-Integration), you only need to use the `container:` parameter. There is no need to set the server.
+  - Example:
+
+    ```
+      - Plex:
+      icon: /icons/plex.png
+      href: https://app.plex.com
+      container: plex
+    ```
+
+- When you upload a new image in to the **/images** folder, you will need to restart the container for it to show up in the WebUI. Please see the [Wiki](https://github.com/benphelps/homepage/wiki/Services#icons) for more information.
