+## Administer Projects
+
+You can administer all projects in the GitLab instance from the Admin Area's Projects page.
+
+To access the Projects page, go to **Admin Area > Overview > Projects**.
+
+Click the **All**, **Private**, **Internal**, or **Public** tab to list only projects of that
+criteria.
+
+By default, all projects are listed, in reverse order of when they were last updated. For each
+project, the name, namespace, description, and size is listed, also options to **Edit** or
+**Delete** it.
+
+Sort projects by **Name**, **Last created**, **Oldest created**, **Last updated**, **Oldest
+updated**, **Owner**, and choose to hide or show archived projects.
+
+In the **Filter by name** field, type the project name you want to find, and GitLab will filter
+them as you type.
+
+Select from the **Namespace** dropdown to filter only projects in that namespace.
+
+You can combine the filter options. For example, click the **Public** tab, and enter `score` in
+the **Filter by name...** input box to list only public projects with `score` in their name.
