+# Sharing a project with a group
+
+If you want to share a single project in a group with another group,
+you can do so easily. By setting the permission you can quickly
+give a select group of users access to a project in a restricted manner.
+
+In a project go to the project settings -> groups.
+
+Now you can select a group that you want to share this project with and with
+which maximum access level. Users in that group are able to access this project
+with their set group access level, up to the maximum level that you've set.
