-# Maintainer's Guide
-
-This document explains how to maintain an image-builder repo.
-
-## How it works
-
-The SD card is automatically built with [Circle](https://circleci.com).
-You don't need real hardware to build and publish the SD card image.
-
-### Pull requests
-
-Pull requests are also built and checked with Circle.
-See the `.circleci/config.yml` file which commands are run for each Git commit.
-The tests defined in `builder/test/` check the SD card image for each Git
-commit and before releasing a new SD card image.
-
-## Draft a new release
-
-You can create a new release directly on GitHub.
-
-Just click on "releases", then click the "Draft a new release" button.
-Please check that you draft a release on "master" branch.
-
-Type in eg. "v1.0.0" into the "Tag version" input field.
-
-Type in eg. "v1.0.0" into the "Release title" input field.
-
-Type in a release description. You may use the text of the previous release
-and adjust it. A release description is important for users of
-[Sibbell](https://sibbell.com) to receive a good notification email or Slack
-message.
-
-You can decide if it's a pre-release with the checkbox at the bottom.
-
-Then press "Publish release".
-
-After that Circle starts a new tagged build with that version tag and also
-runs the deploy steps defined in `.circleci/config.yml` and pushes the SD card image
-to the GitHub release.
