+## Husky for Git Hooks
+
+We are using the package `Husky` to automatically run the following scripts on your changes whenever you make a commit:
+
+```
+yarn format:fix
+yarn lint:fix
+yarn typecheck
+```
+
+This is done to improve developer experience and to make sure that your commits do not fail on the automated workflow runs. Still you can manually opt-out of the same using the `--no-verify` flag as follows:
+
+```
+git commit -m "Commit message" --no-verify
+```
