+## Usage with regex
+
+In order to check the branch name with a regex you can add a a regex as a string under the branchNameLinter in your config JSON.
+
+```
+{
+    "branchNameLinter": {
+		"regex": "^([A-Z]+-[0-9]+.{5,70})"
+		...
+		"msgDoesNotMatchRegex": "Branch \"%s\" must contain certain characters \"%s\"."
