 This mnemonic should only be used for testing.
 
+### Docker
+
+The Request Node can be deployed with Docker.
+For now, the user has to clone the repository to build the Docker and run it.
+
+```bash
+git clone https://github.com/RequestNetwork/requestNetwork.git
+cd packages/request-node
+docker build -t "request-node" .
+docker run request-node
+```
+
+The environment variables used to configure the Node can be defined in the `docker run` command.
+
+For example, the user can define custom parameters for IPFS connection with the following command:
+
+```
+docker run -e IPFS_HOST=<custom_ipfs_host> IPFS_PORT=<custom_ipfs_port>
+``` 
+
+If the user want the server to listen on a specific port, he has to expose that port as well:
+
+```
+docker run -e PORT=80 --expose 80
+```
+
+The user can use the docker-compose tool to run an environment containing the Request Node and an instance of IPFS with the following command:
+
+```bash
+docker-compose up
+```
+
+The environment variables must be defined in the `docker-compose.yml` file in the `environment` section. `$ETHEREUM_NETWORK_ID` and `$WEB3_PROVIDER_URL` must be defined.
