+### Import Merge Requests information

+![Badge Gitlab only](https://img.shields.io/badge/GitLab_Only-8A2BE2?logo=gitlab)
+
+It is possible to extract MergeRequests of a project.
+To avoid too many REST API requests, you should do it in multiple steps.
+
+First, import basic information.
+
+```st
+(glhModel allWithType: GLHProject) do: [:project | 
+  glhImporter importMergeRequests: project
+]
+```
+
+> This will only import the first 20 merge requests for each project. However, one can also use the method `` to import all merge request since a specific date
+
+Then, you can import more data for each MergeRequest
+
+```st
+(glphModel allWithType: GLPHEMergeRequest) do: [ :mr |
+  "Extract information about Merge Request approvals and review"
+  glhImporter importMergeResquestApprovals: mr.
+  "Extract information about Author, Mergers, etc."
+  glhImporter importMergeResquestAuthor: mr.
+].
+```
