-If you use GitHub Actions, you can use [`github-actions-cpu-cores`](https://github.com/SimenB/github-actions-cpu-cores) to detect number of CPUs, and pass that to Jest.
-
-```yaml
-- name: Get number of CPU cores
-  id: cpu-cores
-  uses: SimenB/github-actions-cpu-cores@v1
-- name: run tests
-  run: yarn jest --max-workers ${{ steps.cpu-cores.outputs.count }}
-```
-
 Another thing you can do is use the [`shard`](CLI.md#--shard) flag to parallelize the test run across multiple machines.

 ## `coveragePathIgnorePatterns` seems to not have any effect.
 
 Make sure you are not using the `babel-plugin-istanbul` plugin. Jest wraps Istanbul, and therefore also tells Istanbul what files to instrument with coverage collection. When using `babel-plugin-istanbul`, every file that is processed by Babel will have coverage collection code, hence it is not being ignored by `coveragePathIgnorePatterns`.
