 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.
 
-The example below follows [pnpm recommendations](https://pnpm.io/continuous-integration#github-actions) for installing pnpm and caching the [pnpm store](https://pnpm.io/cli/store). Follow the [Cypress pnpm configuration instructions](https://on.cypress.io/install#pnpm-Configuration) and apply them to your project, to enable pnpm to install the Cypress binary.
