 GitHub automated CI package builds
 ==================================

+Freely available GitHub Action continous integration (CI) build and test services for open source
+repositories are provided by `GitHub <https://github.com/>`_. These services will build and test the C++ code for your module and also generate Linux,
 macOS, and Windows Python packages for your module.
 
-After enabling builds for the GitHub repository with a `CircleCI
-<https://circleci.com/>`_, `TravisCI <https://travis-ci.org/>`_,
-and `AppVeyor <https://www.appveyor.com/>`_ account, Python wheel
-packages will be available with the continuous integration builds.
-These services use the configurations generated by the `ITKModuleTemplate <https://github.com/InsightSoftwareConsortium/ITKModuleTemplate>`_.
+For every pull request and push to the GitHub repository, a GitHub Action will
+run that builds and runs the repository's C++ tests and reports the results to
+the [ITK CDash Dashboard](https://open.cdash.org/index.php?project=Insight).
+Python packages are also generated for every commit. Packages for a commit's
+build can be downloaded from the GitHub Action result page in the *Artifacts*
+Section.

+Upload the packages to PyPI
+----------------------------
+
+First, `register for an account on PyPI <https://pypi.org>`_.
+
+Next, create a `~/.pypirc` file with your login credentials::
+
+  [distutils]
+  index-servers =
+    pypi
+    pypitest
+
+  [pypi]
+  username=<your-username>
+  password=<your-password>
+
+  [pypitest]
+  repository=https://test.pypi.org/legacy/
+  username=<your-username>
+  password=<your-password>
+
+where `<your-username>` and `<your-password>` correspond to your PyPI account.
+
+Then, upload wheels to the testing server::
+
+  python -m pip install twine
+  python -m twine upload -r pypitest dist/*
+
+Check out the packages on `<https://test.pypi.org/>`_ the testing server.
+
+Finally, upload the wheel packages to the production PyPI server::
+
+  python -m twine upload dist/*
+
+Congratulations! Your packages can be installed with the commands::
+
+  python -m pip install --upgrade pip
+  python -m pip install itk-<yourmodulename>
+
+Automate PyPI Package Uploads
+-----------------------------
+
+Automated uploads of Python packages to the Python package index,
+[PyPI](https://pypi.org) will occur after adding a PyPI upload token to GitHub
+and creating a Git tag.
+

-  :alt: TravisCI Python wheels
+Then, add the API token to the GitHub repository's *Settings -> Secrets* page
+in a key called *pypi_password*. Note that this will be a *token* instead of a
+password. Limit the scope of the token to the individual package as a best
+practice.
 
-  macOS Python package wheels can be downloaded by visiting to the `file.io`
-  link found in the build output. Note: this link may only be valid for the
-  initial download.

+To push packages to PyPI, first, make sure to update the `version` for your
+package in the *setup.py* file. Then create a Git tag corresponding to the
+version. A Git tag can be created in the GitHub user interface via
+*Releases -> Draft a new release*.
 
-  Windows Python package wheel links can be found in the AppVeyor *Artifacts* tab.
