Updating patch status
~~~~~~~~~~~~~~~~~~~~~
-It may be tempting to help the maintainers and update the state of your
-own patches when you post a new version or spot a bug. Please **do not**
-do that.
-Interfering with the patch status on patchwork will only cause confusion. Leave
-it to the maintainer to figure out what is the most recent and current
-version that should be applied. If there is any doubt, the maintainer
-will reply and ask what should be done.
+Contributors and reviewers do not have the permissions to update patch
+state directly in patchwork. Patchwork doesn't expose much information
+about the history of the state of patches, therefore having multiple
+people update the state leads to confusion.
+
+Instead of delegating patchwork permissions netdev uses a simple mail
+bot which looks for special commands/lines within the emails sent to
+the mailing list. For example to mark a series as Changes Requested
+one needs to send the following line anywhere in the email thread::
+
+ pw-bot: changes-requested
+
+As a result the bot will set the entire series to Changes Requested.
+This may be useful when author discovers a bug in their own series
+and wants to prevent it from getting applied.
+
+The use of the bot is entirely optional, if in doubt ignore its existence
+completely. Maintainers will classify and update the state of the patches
+themselves. No email should ever be sent to the list with the main purpose
+of communicating with the bot, the bot commands should be seen as metadata.
+
+The use of the bot is restricted to authors of the patches (the ``From:``
+header on patch submission and command must match!), maintainers themselves
+and a handful of senior reviewers. Bot records its activity here:
+
+ https://patchwork.hopto.org/pw-bot.html
