 # Writing Documentation
 
   - **General Documentation**: written by the developers responsible by creating features. Should be submitted in the same merge request containing code. Feature proposals (by GitLab contributors) should also be accompanied by its respective documentation. They can be later improved by PMs and Technical Writers.
-  - **Technical Articles**: written by any GitLab Team member, GitLab contributors, or [Community Writers](https://about.gitlab.com/handbook/product/technical-writing/community-writers/).
+  - **Technical Articles**: written by any [GitLab Team](https://about.gitlab.com/team/) member, GitLab contributors, or [Community Writers](https://about.gitlab.com/handbook/product/technical-writing/community-writers/).
   - **Indexes per topic**: initially prepared by the Technical Writing Team, and kept up-to-date by developers and PMs, in the same merge request containing code.
