 If this is set to true (default is false) then all merge requests will be migrated as GitHub issues (rather than pull requests). This can be
 used to sidestep the problem where pull requests are rejected by GitHub if the feature branch no longer exists or has been merged.
 
+#### filterByLabel
+
+Filters all merge requests and issues by these labels. The applicable values can be found in the Gitlab API documentation for [issues](https://docs.gitlab.com/ee/api/issues.html#list-project-issues) and [merge requests](https://docs.gitlab.com/ee/api/merge_requests.html#list-merge-requests) respectively. Default is `null` which returns all issues/merge requests.

 #### skipMatchingComments
 
 This is an array (empty per default) that may contain string values. Any note/comment in any issue, that contains one or more of those string values, will be skipped (meaining not migrated). Note that this is case insensitive, therefore the string value `foo` would also lead to skipping notes containing a (sub)string `FOO`.
