 ## Implement design & UI elements
 
-Please see the [UX Guide for GitLab].
+For guidance on UX implementation at GitLab, please refer to our [Design System](https://design.gitlab.com/).
+
+The UX team uses labels to manage their workflow.
+
+The  ~"UX" label on an issue is a signal to the UX team that it will need UX attention. 
+To better understand the priority by which UX tackles issues, see the [UX section](https://about.gitlab.com/handbook/ux/) of the handbook.
+
+Once an issue has been worked on and is ready for development, a UXer applies the ~"UX ready" label to that issue.
+
+The UX team has a special type label called ~"design artifact". This label indicates that the final output 
+for an issue is a UX solution/design. The solution will be developed by frontend and/or backend in a subsequent milestone. 
+Any issue labeled ~"design artifact" should not also be labeled ~"frontend" or ~"backend" since no development is 
+needed until the solution has been decided.
+
+~"design artifact" issues are like any other issue and should contain a milestone label, ~"Deliverable" or ~"Stretch", when scheduled in the current milestone.
+
+Once the ~"design artifact" issue has been completed, the UXer removes the ~"design artifact" label and applies the ~"UX ready" label. The Product Manager can use the 
+existing issue or decide to create a whole new issue for the purpose of development.

+### Restore for Docker image and gitlab-omnibus helm chart
+
+For GitLab installations using docker image or the gitlab-omnibus helm chart on
+a Kubernetes cluster, restore task expects the restore directories to be empty.
+However, with docker and Kubernetes volume mounts, some system level directories
+may be created at the volume roots, like `lost+found` directory found in Linux
+operating systems. These directories are usually owned by `root`, which can
+cause access permission errors since the restore rake task runs as `git` user.
+So, to restore a GitLab installation, users have to confirm the restore target
+directories are empty.
+
+For both these installation types, the backup tarball has to be available in the
+backup location (default location is `/var/opt/gitlab/backups`).
+
+For docker installations, the restore task can be run from host using the
+command
+
+```
+docker exec -it <name of container> gitlab-rake gitlab:backup:restore
+```
+
+Similarly, for gitlab-omnibus helm chart, the restore task can be run on the
