From 758fe3ef8baa68e71f766ae5499dfa6988d0d72a Mon Sep 17 00:00:00 2001
From: Vika Shleina <vika@fireburn.ru>
Date: Wed, 21 Jul 2021 06:25:15 +0300
Subject: Added an internal token mechanism

The internal token is a shared secret that can update and delete any
posts stored in the database. It is intended for use in webmention
endpoints to update posts with latest webmentions.

Please keep it safe.
