+# Docker services for server and web client
+
+For convenience, all services required for running the F-UJI server and a simple web client have been bundled up in [`compose.yml`](./compose.yml):
+- `fuji-server` runs the API server
+- `nginx` and `php` provide the web interface
+
+To start, make sure you have Docker installed on your system (refer to the [official documentation](https://docs.docker.com/engine/install/) for details).
+
+## Configuration
+
+Open [`fuji/fuji_server/config/users.py`](../../fuji_server/config/users.py) and set a username and password.
+Set the same username and password in [`index.php`](./index.php#L51) in the variables `$fuji_username` and `$fuji_password`.
+
+Optionally, follow the instructions in the [root README](../../README.md#github-api) to set up authorisation with GitHub.
+
+## Build
+
+Next, build the API server image.
+Navigate to the root of this repository and run `docker build -t fuji-ext .`.
+This should use the [`Dockerfile`](../../Dockerfile) at the root of the repository.
+
+With that done, navigate back to this directory (`fuji/simpleclient/docker`) and run `docker compose up -d`.
+The web client will be available on `localhost:80`.
