+BACKUP REGISTER                                  *gitlab.nvim.backup-register*
+
+Sometimes, the action triggered by `settings.popup.perform_action` can fail.
+To prevent losing your carefully crafted note/comment/suggestion you can set
+`settings.popup.backup_register` to a writable register (see |registers|) to
+which the contents of the popup window will be saved just before the action is
+performed. A practical setting is `settings.popup.backup_register = "+"` which
+saves to the system clipboard (see |quoteplus|). This lets you easily apply
+the action on Gitlab in a browser, if it keeps failing in `gitlab.nvim`. 
+
+If you experience such problems, please first read the
+|gitlab.nvim.troubleshooting| section. If it does not help, see if there are
+any relevant known <https://github.com/harrisoncramer/gitlab.nvim/issues>. If
+there are none, please open one and provide any error messages that
+`gitlab.nvim` may be showing.
