 ### Deployment
-To deploy the backend docker container, we use kubernetes. Modifications to the backend are automatically pushed to a two-stage environment through the CI pipeline. See [deployment/README](deployment/README.md] for further information.

-The deployment configuration is included as a submodule in the `deployment` directory. The standalone repository is under [https://git.kluster.moll.re/anydev/anyway-backend-deployment/](https://git.kluster.moll.re/anydev/anyway-backend-deployment/).
