+## Docker quick start
+Docker image of geneth is now available on
+https://hub.docker.com/r/genechain/geneth. You can get GeneChain up and running

+
+```
+docker run -d --name genechain-node -v /Users/alice/genechain:/root \
+           -p 8545:8545 -p 30303:30303 \
+           genechain/geneth
+```
+
+Remember to replace `/Users/alice/genechain` with a path to the folder where you
+want your blockchain to be stored.
+
+If you want to access RPC from other containers and/or hosts, append
+`--http.addr 0.0.0.0` to the docker command. More on running `geneth` can be
