-Some older **external** examples, linked to by this document, are based solely on Cypress 9 and below and therefore use a [Legacy Configuration](https://on.cypress.io/guides/references/legacy-configuration). These may need modification to be applied to Cypress 10 and later. Each of these external links is listed with a `(legacy)` notation.
+Older **external** examples based on a [Legacy Configuration](https://on.cypress.io/guides/references/legacy-configuration) for Cypress `9` and earlier can be found in the [README](https://github.com/cypress-io/github-action/blob/v5/README.md) for version `v5`.
 
 **Note:** this package assumes that [cypress](https://www.npmjs.com/package/cypress) is declared as a development dependency in the [package.json](https://docs.npmjs.com/creating-a-package-json-file) file. The [cypress npm module](https://www.npmjs.com/package/cypress) is required to run Cypress via its [Module API](https://on.cypress.io/module-api).

 ### pnpm
 
 The package manager `pnpm` is not pre-installed in [GitHub Actions runner images](https://github.com/actions/runner-images) (unlike `npm` and `yarn`): to install `pnpm` include [pnpm/action-setup](https://github.com/pnpm/action-setup) in your workflow. 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.

 ### Custom install
 
-Finally, you might not need this GH Action at all. For example, if you want to split the npm dependencies installation from the Cypress binary installation, then it makes no sense to use this action. Instead you can install and cache Cypress yourself. See [cypress-gh-action-split-install](https://github.com/bahmutov/cypress-gh-action-split-install) (legacy) for a working example.
