+Honk administration guide.
+
+This is the admin manual. Please refer to manual.txt for user documentation.
+
+-- css
+
+Custom CSS may be provided by creating a views/local.css file.
+
+-- message
+
+A custom server message may be set adding a ('servermsg', 'message') entry to
+the config table using sqlite3.
+
+-- emus and memes
+
+Custom emus may be provided by creating and populating the emus directory.
+emus may be referenced when composing a honk via colon wrapping. How pleasant.
+This :example: will be replaced by emus/example.png.
+
+To save disk space and avoid repeated uploads, the memes directory may be
+prepopulated with bandwidth wasting reactions and referenced by meme: filename.
+
+A list of available emus and memes appears in the funzone.
+
+-- cleanup
+
+One should occasionally run `honk cleanup` to free up internal space in the
+database. This deletes honks older than 30 days, but not those posted by a
+user.
+
+One may also run `honk reduce [honker]` to delete honks older than 3 days.
+This is useful to reduce the space requirements from following image bots.
+
+(Neither command runs vacuum, so the file size will not immediately shrink.)
+
+-- add user
+
+Running `honk adduser` can add additional users. This is discouraged.
+
+-- proxy
+
+honk requires a TLS terminating reverse proxy be configured. It communicates
+with other servers via https URLs.
+
+If the proxy is configured to support caching, be mindful of the fact that
+ActivityPub requests vary based on the Accept and Content-Type headers.
+
+ActivityPub in practice uses HTTP signatures to verify requests. In order for
+this to work, the backend server must receive certain header fields
+unmodified. In particular, the Host header and the message content cannot be
+altered.
+
+Specifically, for nginx: `proxy_set_header Host $http_host;`
