 **Warning ⚠️:** Cypress actions use `GITHUB_TOKEN` to get the correct branch and the number of jobs run, making it possible to re-run without the need of pushing an empty commit. If you don't want to use the `GITHUB_TOKEN` you can still run your tests without problem with the only note that Cypress Dashboard API connects parallel jobs into a single logical run using GitHub commit SHA plus workflow name. If you attempt to re-run GitHub checks, the Dashboard thinks the run has already ended. In order to truly rerun parallel jobs, push an empty commit with `git commit --allow-empty -m "re-run checks" && git push`. As another work around you can generate and cache a custom build id, read [Adding a unique build number to GitHub Actions](https://medium.com/attest-engineering/adding-a-unique-github-build-identifier-7aa2e83cadca)
 
+The Cypress GH Action does not spawn or create any additional containers - it only links the multiple containers spawned using the matrix strategy into a single logical Dashboard run and into splitting the specs amongst the machines. See the [Cypress parallelization](https://on.cypress.io/parallelization) guide for the explanation.
