+### Helper Scripts
+
+**[scripts/TagVersion.ps1](./scripts/TagVersion.ps1)** creates a version tag on the main branch or any other specified branch. The tag assigned to the branch is calculated by GitVersion. Version number assigned can also be modified, e.g. any part of SemBer can be forcibly increased. This script is intended for use on the local repository.
