 # version-check
-Checks if version is upgraded when updating the repository
+Checks if version is upgraded when updating the repository. Pass regex for version strings and a filename to test if it has been updated.
+
+## Set version format regex
+
+I use ruby regex (rubular) for the version strings. The default value is `/[v]\d.\d.\d/` (which means e.g. v1.0.0). You can test your own formats at: https://rubular.com/.
