+# README:
+#
+# The semantics for running shell commands in GitHub actions is non-obvious. Please read
+# https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstepsshell
+# before modifying this file. Our strategy is to rely on the built-in (unspecified) shell, and
+# explicitly set the shell settings we want (with `set -eo pipefail`) at the beginning of any
+# bash script. For more information on these settings, see `man bash`.
+#
+# GitHub Actions files can be difficult to modify with confidence, because testing changes often
+# requires pushing to a branch and running CI remotely. To make this process easier, consider
+# the following:
+#
+# 1) Use Visual Studio Code with the GitHub Actions Extension (github.vscode-github-actions).
+#    This allows you to check the validity of your action schema and syntax without pushing to a
+#    branch.
+# 2) Use https://github.com/nektos/act to run your CI steps locally. Note this will only work with
+#    steps run on Linux platforms, as `act` is implemented with Docker containers.
