+# Deploy Focalboard with Docker
+
+## Docker
+
+The Dockerfile gives a quick and easy way to pull the latest Focalboard server and deploy it locally.
+
+```
+docker build -t focalboard .
+docker run -it -p 80:8000 focalboard
+```
+
+Open a browser to http://localhost to start
+
+## Docker-Compose
+
+Docker-Compose provides the option to automate the build and run step, or even include some of the steps from the [personal server setup](https://www.focalboard.com/download/personal-edition/ubuntu/).
+
+To start the server run
+
+```
+docker-compose up
+``` 
+
+This will automatically build the focalboard image and start it with the http port mapping.
+
+To run focalboard with a nginx proxy and a postgres backend run
+
+```
+docker-compose -f docker-compose-db-nginx.yml up
+```
