+## Using dockerhub for development
+
+Merges to master are automatically deployed to dockerhub at
+[https://hub.docker.com/r/hyperledger/iroha-docker/](https://hub.docker.com/r/hyperledger/iroha-docker/), so it is possible to pull from there to start up a network with 4 servers. Currently only 4 servers are supported. Using this method, it is possible set up a network within a few minutes.
