+# Release Instructions
+
+Before creating a new release carefully consider the version number of the new
+release. We are following [Semantic Versioning](https://semver.org/) and
+[PEP440](https://www.python.org/dev/peps/pep-0440/).
+
+## Preparing the Required Python Packages
+
+* Install twine for pypi package uploads
+
+  ```sh
+  python3 -m pip install --user --upgrade twine
+  ```
+
+## Configuring the Access to the Python Package Index (PyPI)
+
+*Note:* This is only necessary for users performing the release process for the
+first time.
+
+* Create an account at [Test PyPI](https://packaging.python.org/guides/using-testpypi/).
+
+* Create an account at [PyPI](https://pypi.org/).
+
+* Create a pypi configuration file `~/.pypirc` with the following content (Note:
+  `<username>` must be replaced):
+
+  ```ini
+  [distutils]
+  index-servers =
+      pypi
+      testpypi
+
+  [pypi]
+  username = <username>
+
+  [testpypi]
+  repository = https://test.pypi.org/legacy/
+  username = <username>
+  ```
+
+## Prepare testing the Release
+
+* Fetch upstream changes and create a branch:
+
+  ```sh
+  git fetch upstream
+  git checkout -b create-new-release upstream/master
+  ```
+
+* Get the current version number
+
+  ```sh
+  poetry run python -m pontos.version show
+  ```
+
+* Update the version number to some alpha version e.g.
+
+  ```sh
+  poetry run python -m pontos.version update 1.2.3a1
+  ```
+
+## Uploading to the PyPI Test Instance
+
+* Create a source and wheel distribution:
+
+  ```sh
+  rm -rf dist build ospd.egg-info
+  poetry build
+  ```
+
+* Upload the archives in `dist` to [Test PyPI](https://test.pypi.org/):
+
+  ```sh
+  twine upload -r testpypi dist/*
+  ```
+
+* Check if the package is available at <https://test.pypi.org/project/ospd>.
+
+## Testing the Uploaded Package
+
+* Create a test directory:
+
+  ```sh
+  mkdir ospd-install-test
+  cd ospd-install-test
+  python3 -m venv test-env
+  source test-env/bin/activate
+  pip install -U pip  # ensure the environment uses a recent version of pip
+  pip install --pre -I --extra-index-url https://test.pypi.org/simple/ ospd
+  ```
+
+* Check install version with a Python script:
+
+  ```sh
+  python3 -c "from ospd import __version__; print(__version__)"
+  ```
+
+* Remove test environment:
+
+  ```sh
+  deactivate
+  cd ..
+  rm -rf ospd-install-test
+  ```
+
+## Prepare the Release
+
+* Determine new release version number
+
+  If the output is something like  `1.2.3.dev1` or `1.2.3a1`, the new version
+  should be `1.2.3`.
+
+* Update to new version number (`<new-version>` must be replaced by the version
+  from the last step)
+
+  ```sh
+  cd path/to/git/clone/of/ospd
+  poetry run python -m pontos.version update <new-version>
+  ```
+
+* Update the `CHANGELOG.md` file:
+  * Change `[unreleased]` to new release version.
+  * Add a release date.
+  * Update reference to Github diff.
+  * Remove empty sub sections like *Deprecated*.
+
+* Create a git commit:
+
+  ```sh
+  git add .
+  git commit -m "Prepare release <version>"
+  ```
+
+## Performing the Release on GitHub
+
+* Create a pull request (PR) for the earlier commit:
+
+  ```sh
+  git push origin
+  ```
+  Open GitHub and create a PR against <https://github.com/greenbone/ospd>.
+
+* Ask another developer/maintainer to review and merge the PR.
+
+* Once the PR is merged, update the local `master` branch:
+
+  ```sh
+  git fetch upstream
+  git rebase upstream/master master
+  ```
+
+* Create a git tag:
+
+  ```sh
+  git tag v<version>
+  ```
+
+  Or even a tag signed with a personal GPG key:
+
+  ```sh
+  git tag --sign --message "Tagging the <version> release" v<version>
+  ```
+
+* Push changes and tag to Github:
+
+  ```sh
+  git push --tags upstream
+  ```
+
+## Uploading to the 'real' PyPI
+
+* Uploading to PyPI is done automatically by pushing a git tag via CircleCI
+
+* Check if new version is available at <https://pypi.org/project/ospd>.
+
+## Bumping `master` Branch to the Next Version
+
+
+* Update to a Development Version
+
+  The next version should contain an incremented minor version and a dev suffix
+  e.g. 2.3.0.dev1
+
+  ```sh
+  poetry run python -m pontos.version update <next-dev-version>
+  ```
+
+* Create a commit for the version bump:
+
+  ```sh
+  git add .
+  git commit -m "Update version after <version> release"
+  git push upstream
+  ```
+
+## Announcing the Release
+
+* Create a Github release:
+
+  See https://help.github.com/articles/creating-releases/
