 You need to run [c-lightning](https://github.com/ElementsProject/lightning) and [Lightning Charge](https://github.com/ElementsProject/lightning-charge) somewhere.
 
+## Deploy with Docker
+
+Install [Docker](https://docs.docker.com/install/).
+
+Work in progress. For now it just launches `bitcoind`:
+
+```sh
+docker run --rm --name matreon --mount source=matreon-vol,destination=/home/bitcoin/.bitcoin -it provoost/matreon:latest -printtoconsole
+```
+
 ## Deploy to Heroku
 
 Create a new Heroku app `app-name` and add the Sendgrid Add-On.
