+# `dist/index.js` is a special file in Actions.
+# When you reference an action with `uses:` in a workflow,
+# `index.js` is the code that will run.
+# For our project, we generate this file through a build process from other source files.
+# We need to make sure the checked-in `index.js` actually matches what we expect it to be.
