+## Production build
+
+For production usage, there are prepared docker images on the [DockerHub](https://hub.docker.com/r/68publishers/cmp/tags).
+
+Two images are published with each new version of the application:
+
+- `68publishers/cmp:app-{version}` - the container with the application
+- `68publishers/cmp:worker-{version}` - the container with the worker
+
+The images are already build, they contain all libraries, assets and so on. So there should be no need to manually install or build anything into them.
