-# Bazel continous integration setup
-
-This workspace contains the setup for the continuous integration
-system of Bazel. This setup is based on docker images built by bazel.
-
-## For users of Bazel continuous integration system
-
-If you are a user of the CI system, you might be interested in the
-following document:
-
-* [owner](docs/owner.md): explains how to add a job for a repository
- owner.
-* [user](docs/user.md): explains how to use the CI system for a Bazel
- contributor.
-
-## For maintainers of Bazel continuous integration system
-
-Make sure you have a Bazel installed with a recent enough version of
-it. Also make sure [gcloud](https://cloud.google.com/sdk/) and
-[docker](https://www.docker.com) are correctly configured on your
-machine. Only docker version 1.10 or later is supported.
-
-Finally, our docker rules needs authentication which is configured with the
-[credential helper](https://github.com/GoogleCloudPlatform/docker-credential-gcr):
-
-```bash
-gcloud components install docker-credential-gcr
-export DOCKER_CONFIG="$(docker-credential-gcr configure-docker | sed -E 's|/config.json .*$||')"
-```
-
-You might want to permanently set your `DOCKER_CONFIG` environment, e.g. in your
-`~/.bash_profile`:
-
-```bash
-echo "export DOCKER_CONFIG='${DOCKER_CONFIG}'" >> ~/.bash_profile
-```
-
-More documentation:
-
-* [`init.sh`](docs/init.md): initializes the whole CI platform. This
- may delete VMs and do other irreversible changes, so handle with
- care.
-* [`vm.sh`](docs/machines.md): lets you control the machines
- (e.g. start/stop them, create/delete/reimage them), including
- the Jenkins controller and the executor nodes.
-* [workflow](docs/workflow.md): explains the CI workflow
-* [jobs](docs/jobs.md): explains what jobs are running on the CI
