+# This workflow runs whenever a PR is opened or updated, or a commit is pushed to main. It runs
+# several checks:
+# - fmt: checks that the code is formatted according to rustfmt
+# - clippy: checks that the code does not contain any clippy warnin
+# - test: runs the tests
+
+# This configuration allows maintainers of this repo to create a branch and pull request based on
+# the new branch. Restricting the push trigger to the main branch ensures that the PR only gets
