 ### pnpm
 
 The package manager `pnpm` is not pre-installed in [GitHub Actions runner images](https://github.com/actions/runner-images) (unlike `npm` and `yarn`) and so it must be installed in a separate workflow step (see below). If the action finds a `pnpm-lock.yaml` file, it uses the [pnpm](https://pnpm.io/cli/install) command `pnpm install --frozen-lockfile` by default to install dependencies.
-At this time the action does not automatically cache dependencies installed by pnpm. The example below includes steps to locate the pnpm store directory and to cache its contents for later use.
+At this time, the action does not automatically cache dependencies installed by pnpm. We advise against attempting to work around this restriction, by caching the pnpm store directory through additional workflow steps, as this can lead to the action skipping installation of the Cypress binary, causing workflow failure.
