 ## Why here?
 This repository is here to support the Gitleaks action with all the updates from [Gitleaks source project](https://github.com/zricethezav/gitleaks). With the new 2.0 version of [gitleaks/gitleaks-action GitHub Action](https://github.com/gitleaks/gitleaks-action#-why-is-my-gitleaks-action-job-suddenly-failing) they went to a commercial licence.
