      # Note!
      # We need to install all node modules in each of the 3 directories.
      # 1. content-origin-request
      # 2. content-origin-response
      # 3. tests
      #
      # If we don't do this, you can't do things like:
      #
      #    const { handler } = require("../content-origin-request");
      #
      # The reason `yarn install` won't pick up the sub-dependencies
      # is because these 3 directories don't share a common root.
