+  #### Temporal UI Server Configuration
+
+  Temporal UI server must be provided with a configuration file to start up successfully. We do not include any default configurations in the image. Instead, we expect the user to either add a configuration file in the deployed container or mount a volume with the config file in the container.
+
+  Some development configuration files can be found in [the temporal ui repository](https://github.com/temporalio/ui/tree/main/server/config).
+
+  The following outlines steps to mount the development configuration files while launching a container:
+
+  ```sh
+  $ git clone https://github.com/temporalio/ui
+
+  $ docker run -d --name temporal-ui-container -p 8081:8081 -v ./ui/server/config:/home/ui-server/config -e TEMPORAL_ROOT=/home/ui-server -e TEMPORAL_ENVIRONMENT=development ubuntu/temporal-ui:2.39.0-24.04_edge
+  ```
