-Internal Debian archive operations
-----------------------------------
-
-Packages should be uploaded to: 
-
-    alberti.torproject.org:/srv/db.torproject.org/ftp-archive/archive/pool/tpo-all/
-
-Then to install the packages:
-
-    ssh alberti.tpo make -C /srv/db.torproject.org/ftp-archive
-
-This might require fixing some permissions. Do a `chmod g+w` on the
-broken directories if this happens and open a ticket if it does, to
-create a service account instead of that hack.

+Uploading admin packages
+========================
+
+There is a separate Debian archive, on `db.torproject.org`, which can
+be used to upload packages specifically designed to run on
+`torproject.org` infrastructure. The following `.dput.cf` should allow
+you to upload built packages to the server, provided you have the
+required accesses:
+
+    [tpo-admin]
+    fqdn = alberti.torproject.org
+    incoming = /srv/db.torproject.org/ftp-archive/archive/pool/tpo-all/
+    method = sftp
+
+Then to install the packages:
+
+    ssh alberti.torproject.org make -C /srv/db.torproject.org/ftp-archive
