+name: Run Sage CI for Linux/Cygwin/macOS
+
+## This GitHub Actions workflow provides:
+##
+##  - portability testing, by building and testing this project on many platforms
+##    (Linux variants and Cygwin), each with two configurations (installed packages),
+##
+##  - continuous integration, by building and testing other software
+##    that depends on this project.
+##
+## It runs on every pull request and push of a tag to the GitHub repository.
+##
+## The testing can be monitored in the "Actions" tab of the GitHub repository.
+##
+## After all jobs have finished (or are canceled) and a short delay,
+## tar files of all logs are made available as "build artifacts".
+##
+## This GitHub Actions workflow uses the portability testing framework
+## of SageMath (https://www.sagemath.org/).  For more information, see
+## https://doc.sagemath.org/html/en/developer/portability_testing.html
+
+## The workflow consists of two jobs:
+##
+##  - First, it builds a source distribution of the project
+##    and generates a script "update-pkgs.sh".  It uploads them
+##    as a build artifact named upstream.
+##
+##  - Second, it checks out a copy of the SageMath source tree.
+##    It downloads the upstream artifact and replaces the project's
+##    package in the SageMath distribution by the newly packaged one
+##    from the upstream artifact, by running the script "update-pkgs.sh".
+##    Then it builds a small portion of the Sage distribution.
+##
+## Many copies of the second step are run in parallel for each of the tested
+## systems/configurations.
