 ## Installing the library
 
-Add `democorp_airflow` to your `requirements.txt`.
+Since this repository is built only for example purposes, we publish a Python package only to [TestPyPI](https://test.pypi.org/project/democorp-airflow). Therefore, you'll need to add TestPyPI as an (extra) index URL. You can install the package using pip:
+
+```bash
+pip install -i https://test.pypi.org/simple/ democorp-airflow
+```
+
+Or when installing from a requirements.txt file:
+
+```text
+--extra-index-url https://test.pypi.org/simple
+democorp_airflow
+
+# Install with "pip install -r requirements.txt"

 ## Versioning
 
-We use `setuptools-scm` to automatically manage versioning based on git tags. When you create a new tag, the library version is updated accordingly. See [1](https://github.com/pypa/setuptools_scm/), [2](https://www.moritzkoerber.com/posts/versioning-with-setuptools_scm/) for more details.

 ## Continuous Integration/Continuous Deployment (CI/CD)
 
 Our CI/CD pipeline is managed using GitHub Actions:
 
-- On every commit, syntax checks and unit tests are run to ensure code quality.
-- When a new tag is pushed, the library is built (and should be pushed to a registry such as PyPI or Artifactory).
+- On every commit, syntax checks and unit tests are run to ensure code quality. See `.github/workflows/ci.yaml`.
+- When a new tag is pushed, the library is built, published to TestPyPI, and a GitHub release is created. See `.github/workflows/publish.yaml`.
