 Ensure you have Docker and Docker Compose installed on your machine. You can download Docker from [here](https://www.docker.com/get-started) and Docker Compose from [here](https://docs.docker.com/compose/install/).
 
-## Docker Compose Configuration
+You need to have a LND node running locally. We recommend using [Polar](https://lightningpolar.com/) for this.
 
-The `compose.yml` file is configured as follows:
+## Docker Compose Configuration
 
-```yaml
-services:
-  mostro:
-    build:
-      context: ..
-      dockerfile: docker/Dockerfile
-    volumes:
-      - ./config:/config  # settings.toml and mostro.db
-      - ~/.polar/networks/1/volumes/lnd:/lnd # LND data
-    platform: linux/amd64
+The `compose.yml` sets up the following services:
 
-```
+- `mostro`: the MostroP2P service
+- `nostr-relay`: the Nostr relay
 
 ## Building and Running the Docker Container
 
 To build and run the Docker container using Docker Compose, follow these steps:
 
+### Steps for running the MostroP2P service and Nostr relay
+
 1. Clone the repository:
 
    ```sh
    git clone https://github.com/MostroP2P/mostro.git
-   cd mostro/docker
    ```
 
 2. Ensure you have the `settings.toml` configuration file and the `mostro.db` SQLite database in a `config` directory (acording to the `volumes` section). If you don't have those files from a previous installation, then the first time they will be created as follows:
 
-   - `settings.toml` from the settings.docker.toml template
-   - `mostro.db` from (empty) database mostro.empty.db
+   - `docker/config/settings.toml` from the `docker/settings.docker.toml` template
+   - `docker/config/mostro.db` from the `docker/empty.mostro.db` database
+
+3. Set the `LND_CERT_FILE` and `LND_MACAROON_FILE` to the paths of the LND TLS certificate and macaroon files on the `docker/.env` file. These files will be copied to the `docker/config/lnd` directory. For example:
+
+   ```sh
+   LND_CERT_FILE=~/.polar/networks/1/volumes/lnd/alice/tls.cert
+   LND_MACAROON_FILE=~/.polar/networks/1/volumes/lnd/alice/data/chain/bitcoin/regtest/admin.macaroon
+   ```
+
+4. [Optional] Set the `MOSTRO_RELAY_LOCAL_PORT` to the port you want to use for the local relay on the `docker/.env` file. For example:
+
+   ```sh
+   MOSTRO_RELAY_LOCAL_PORT=7000
+   ```
+
+5. Build the docker image:
+
+   ```sh
+   make docker-build
+   ```
+
+6. Run the docker compose file:
+
+   ```sh
+   make docker-up
+   ```
+
+## Stopping the Docker Container
 
-3. Run Docker Compose:
+To stop the Docker container, run:
+
+```sh
+make docker-down
+```
+
+## Steps for running just the Nostr relay
+
+1. Run the following command to start the Nostr relay:
 
    ```sh
-   docker compose up --build -d
+   make docker-relay-up
    ```
 
-This command will build the Docker image and run the container in detached mode.
+2. Stop the Nostr relay:
+
+   ```sh
+   make docker-down
+   ```
