-# Exercism Test Runner Template
+# Exercism ABAP Test Runner

-This repository is a [template repository](https://help.github.com/en/github/creating-cloning-and-archiving-repositories/creating-a-template-repository) for creating [test runners][test-runners] for [Exercism][exercism] tracks.
-
-## Using the Test Runner Template
-
-1. Ensure that your track has not already implemented a test runner. If there is, there will be a `https://github.com/exercism/<track>-test-runner` repository (i.e. if your track's slug is `python`, the test runner repo would be `https://github.com/exercism/python-test-runner`)
-2. Follow [GitHub's documentation](https://help.github.com/en/github/creating-cloning-and-archiving-repositories/creating-a-repository-from-a-template) for creating a repository from a template repository
-   - Name your new repository based on your language track's slug (i.e. if your track is for Python, your test runner repo name is `python-test-runner`)
-3. Remove this [Exercism Test Runner Template](#exercism-test-runner-template) section from the `README.md` file
-4. Build the test runner, conforming to the [Test Runner interface specification](https://github.com/exercism/docs/blob/main/building/tooling/test-runners/interface.md).
-   - Update the files to match your track's needs. At the very least, you'll need to update `bin/run.sh`, `Dockerfile` and the test solutions in the `tests` directory
-   - Tip: look for `TODO:` comments to point you towards code that need updating
-   - Tip: look for `OPTIONAL:` comments to point you towards code that _could_ be useful
-
-Once you're happy with your test runner, [open an issue on the exercism/automated-tests repo](https://github.com/exercism/automated-tests/issues/new?assignees=&labels=&template=new-test-runner.md&title=%5BNew+Test+Runner%5D+) to request an official test runner repository for your track.
