+## CircleCI for Linux host (without custom Docker images)
+
+This CircleCI configuration defines two jobs, `build-linux` and `build-macos`,
+within a workflow named `build`. The `build-linux` job utilizes a Docker image
+with Python 3.12.3, while `build-macos` runs on macOS with Xcode 15.3.0. Each
+job involves checking out the code, installing Meson and Ninja, configuring the
+project, compiling it, and running tests using Meson.

 ## GitHub Actions
 
-GitHub Actions are distinct from Azure Pipelines in their workflow
-syntax. It can be easier to setup specific CI tasks in Actions than
-Pipelines, depending on the particular task. This is an example file:
-.github/workflows/ci_meson.yml supposing the project is C-based, using
-GCC on Linux, Mac and Windows. The optional `on:` parameters only run
-this CI when the C code is changed--corresponding ci_python.yml might
-run only on "**.py" file changes.
+GitHub Actions provides a versatile platform for continuous integration
+(CI). This example workflow file, `ci_meson.yml`, is tailored for C-based
+projects utilizing GCC on Linux, macOS, and Windows. Triggered by changes
+to C code files, it automates building and testing processes using different
+versions of Meson (1.0.0, 1.1.0, 1.2.0, 1.3.0, 1.4.0) across various operating
+systems. Each job in the workflow handles checkout, dependency installation,
+project configuration, test execution, and optional test log uploads upon
+failure.
