+# The build has two stages. The 'container' stage is used to build a Docker
+# container and push it to the project's container registry on fd.o GitLab.
+# This step is only run when the tag for the container changes, else it is
+# effectively a no-op. All of this infrastructure is inherited from the
+# wayland/ci-templates repository which is the recommended way to set up CI
+# infrastructure on fd.o GitLab.
+#
+# Once the container stage is done, we move on to the 'build' stage where we
+# run an autotools and meson build in parallel. Currently, tests are also run
+# as part of the build stage as there doesn't seem to be significant value to
+# splitting the stages at the moment.
