+## Increasing version
+Because package-lock.json version also needs to be updated and we are using bump2version to increase versions which does not work well with multi-line search inside package-lock.json for unknown reason, a two commit procedure to bump the version is needed.
+
+```bash
+npm version --no-git-tag-version <version> # via a postversion command does 'git add' and 'git commit'
+bump2version patch --new-version <version> # a proper bumpversion
+```
