# yaml-language-server: $schema=https://json.schemastore.org/github-workflow.json

# `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.
