 # Project forking workflow
 
-Forking a project to your own namespace is useful if you have no write
-access to the project you want to contribute to. Even if you do have write
-access or can request it, we recommend working together in the same
-repository since it is simpler. See our [GitLab Flow](../../../topics/gitlab_flow.md)
-document more information about using branches to work together.
+Whenever possible, it's recommended to work in a common Git repository and use
+[branching strategies](../../../topics/gitlab_flow.md) to manage your work. However,
+if you do not have write access for the repository you want to contribute to, you

+A fork is a personal copy of the repository and all its branches, which you create
+in a namespace of your choice. This way you can make changes in your own fork and
+submit them through a merge request to the repo you don't have access to.
