+
+The repository is the homebase for all e2e test automation efforts at Eclipse Tractus-X.
+It contains umbrella Helm Chart to deploy a sandbox Catena-X dataspace based on the Tractus-X OSS components, as well as
+automated tests and workflows to verify the end-to-end use cases and the compatibility of the OSS components and versions.
+
+## Testing GitHub workflows locally
+
+If you want to try out your new or improved GitHub workflow locally, before pushing, you can try to use
+[act](https://github.com/nektos/act). Follow the official [installation instructions](https://github.com/nektos/act#installation)
+for your OS/package manager to set it up on your machine.
+
+There is also plenty of documentation on how to use act and simulate events, that would trigger workflow runs on GitHub.
+Some workflows might run into issues, when running them locally. This might be caused by missing values for
+`${{ github.event }}` references. To fix this, you can provide your own [event](https://github.com/nektos/act#installation)
+as `.json` file. There are already examples present in the [/.act](.act) directory.
+
+An local example run via `act` could look like the following: `act -e .act/pr_event.json pull_request`
