+## Undoing room shutdowns
+
+*Note*: This guide may be outdated by the time you read it. By nature of room shutdowns being performed at the database level,
+the structure can and does change without notice.
+
+First, it's important to understand that a room shutdown is very destructive. Undoing a shutdown is not as simple as pretending it
+never happened - work has to be done to move forward instead of resetting the past.
+
+1. For safety reasons, it is recommended to shut down Synapse prior to continuing.
+2. In the database, run `DELETE FROM blocked_rooms WHERE room_id = '!example:example.org';`
+ * For caution: it's recommended to run this in a transaction: `BEGIN; DELETE ...;`, verify you got 1 result, then `COMMIT;`.
+ * The room ID is the same one supplied to the shutdown room API, not the Content Violation room.
+3. Restart Synapse (required).
+
+You will have to manually handle, if you so choose, the following:
+
+* Aliases that would have been redirected to the Content Violation room.
+* Users that would have been booted from the room (and will have been force-joined to the Content Violation room).
+* Removal of the Content Violation room if desired.
