+GitLab is developed for Unix operating systems.
 It does **not** run on Windows, and we have no plans to support it in the near future. For the latest development status view this [issue](https://gitlab.com/gitlab-org/gitlab-ce/issues/46567).
 Please consider using a virtual machine to run GitLab.

 [migrate to PostgreSQL](../update/mysql_to_postgresql.md) instead.
