+Setting up the Development Environment
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+There are three Python tools required to develop, test, and release ics.py:
+
+* `poetry <https://python-poetry.org/>`_ for managing virtualenvs, dependencies,  building, and publishing the package.
+* `tox <https://tox.readthedocs.io/>`_ for running the testsuite and building the documentation.
+* `bump2version <https://pypi.org/project/bump2version/>`_ to help with making a release.
+
+Their respective configuration files are :file:`pyproject.toml`, :file:`tox.ini` and :file:`.bumpversion.cfg`.
+Install the tools via pip:
+
+.. code-block:: bash
+
+    $ pip install tox poetry bump2version --user
+
+.. note::
+    If you want to develop using multiple different Python versions, you might want to consider the
+    `poetry installer <https://python-poetry.org/docs/#installation>`_.
+
+    Poetry will automatically manage a virtualenv that you can use for developing.
+    By default, it will be located centrally in your home directory (e.g. in :file:`/home/user/.cache/pypoetry/virtualenvs/`).
+    To make poetry use a :file:`./.venv/` directory within the ics.py folder, use the following config:
+
+    .. code-block:: bash
+
+        $ poetry config virtualenvs.in-project true
+
+Now you are ready to setup your development environment using the following command:
+
+.. code-block:: bash
+
+    $ poetry install
+
+This will create a new virtualenv and install the dependencies for using ics.py.
+Furthermore, the current source of the ics.py package will be available similar to running :command:`./setup.py develop`.
+To access the virtualenv, use :command:`poetry run python` or :command:`poetry shell`.
+The :file:`poetry.lock` file locks the versions of dependencies in the development environment set up by poetry. This ensures that such an environment is the same for everyone.
+The file :file:`poetry.lock` is only read by poetry and not included in any distributions. These restrictions don't apply when running :command:`pip install ics`.
+As tox manages its own environments and doesn't read the lock file, it installs the latest versions of dependencies for testing.
+More details on the poetry side can be found in the `poetry documentation <https://python-poetry.org/docs/basic-usage/#commit-your-poetrylock-file-to-version-control>`_.
+
+If you made some changes and now want to lint your code, run the testsuite, or build the documentation, run tox.
+You don't have to worry about which versions in which venvs are installed and whether you're directly testing against the sources or against a built package, tox handles all that for you:
+
+.. code-block:: bash
+
+    $ tox
+
+To run a single task and not the whole testsuite, use the ``-e`` flag:
+
+.. code-block:: bash
+
+    $ tox -e docs
+
+To get a list of all available tasks, run :command:`tox -av`.
+
+.. note::
+    If you want to run any tasks of tox manually, make sure you have all the dependencies of the task listed in :file:`tox.ini`.
+    For testing with pytest, this can be done through poetry by installing the ``test`` extra: :command:`poetry install -E test`.
+    Alternatively, you can also let tox `set up <https://tox.readthedocs.io/en/latest/example/devenv.html#creating-development-environments-using-the-devenv-option>`_ your development environment or re-use one of its test environments:
+
+    .. code-block:: bash
+
+        $ tox -e py38
+        $ source .tox/py38/bin/activate
+        (py38) $ pytest
+
+    This also works without having poetry installed.

+How to make a new release
+-------------------------
+
+If you want to publish a new release, use the following steps
+
+.. code-block:: bash
+
+    # Grab the sources and install the dev tools
+    git clone https://github.com/C4ptainCrunch/ics.py.git && cd ics.py
+    pip install tox poetry bump2version --user
+
+    # Make sure all the test run
+    tox && echo "Ready to make a new release" \
+        || echo "Please fix all the tests first"
+
+    # Bump the version and make a "0.8.0-dev -> 0.8.0 (release)" commit
+    bump2version --verbose release
+    # Build the package
+    poetry build
+    # Ensure that the version numbers are consistent
+    tox --recreate
+    # Check changelog and amend if necessary
+    vi CHANGELOG.rst && git commit -i CHANGELOG.rst --amend
+    # Publish to GitHub
+    git push && git push --tags
+    # Publish to PyPi
+    poetry publish
+
+    # Bump the version again to start development of next version
+    bump2version --verbose minor # 0.8.0 (release) -> 0.9.0-dev
+    # Start new changelog
+    vi CHANGELOG.rst && git commit -i CHANGELOG.rst --amend
+    # Publish to GitHub
+    git push && git push --tags
+
+Please note that bump2version directly makes a commit with the new version if you don't
+pass ``--no-commit`` or ``--dry-run``,
+but that's no problem as you can easily amend any changes you want to make.
+Further things to check:
+
+* Check GitHub and PyPi release pages for obvious errors
+* Build documentation for the tag v{version} on rtfd.org
+* Set the default rtfd version to {version}
