 ### What is a git hook?
 
 A git hook is a command or script that is going to be run every time you perform a git action, like `git commit` or `git push`.
-

 If the execution of a git hook fails, then the git action aborts.
 
 For example, if you want to run `linter` on every commit to ensure code quality in your project, then you can create a `pre-commit` hook that would call `npx lint-staged`.

 ### When migrating from `husky` git hooks are not running
