+## Available Docker images
+
+In case you need to use or deploy gaia as a container you could skip the `build` steps and use the official images, $TAG stands for the version you are interested in:
+- `docker run -it -v ~/.gaiad:/root/.gaiad -v ~/.gaiacli:/root/.gaiacli tendermint:$TAG gaiad init`
+- `docker run -it -p 26657:26657 -p 26656:26656 -v ~/.gaiad:/root/.gaiad -v ~/.gaiacli:/root/.gaiacli tendermint:$TAG gaiad start`
+- ...
+- `docker run -it -v ~/.gaiad:/root/.gaiad -v ~/.gaiacli:/root/.gaiacli tendermint:$TAG gaiacli version`
+
+The same images can be used to build your own docker-compose stack.
