+The reflog will cover all recent actions (HEAD reflog records branch switching

+see linkgit:git-log[1].
+
+The reflog is useful in various git commands, to specify the old value
+of a reference. For example, `HEAD@\{2\}` means "where HEAD used to be
+two moves ago", `master@\{one.week.ago\}` means "where master used to
+point to one week ago", and so on. See linkgit:git-rev-parse[1] for
+more details.

+To delete single entries from the reflog, use the subcommand "delete"
+and specify the _exact_ entry (e.g. ``git reflog delete master@\{2\}'').
