+Database(s) structure
+=====================
+
+We have a single postgres instance on ``db`` container. ``tt-rss`` has its own
+database ``tt-rss`` (?). There will be another one for the app that keeps all
+together.
+
+feedati
+-------
+
+The db structure is, right now, the following:
+
+======== ======= ======= =========
+ Schema   Name    Type     Owner
+======== ======= ======= =========
+ public   users   table   postgres
+======== ======= ======= =========
+
+The following statements create the db and the table:
+
+.. code:: sql
+
+   CREATE DATABASE feedati WITH ENCODING=UTF8 OWNER=postgres;
+
+Then create the table:
+
+.. code:: sql
+
+   CREATE EXTENSION IF NOT EXIST "uuid-ossp";
+   CREATE TABLE users
+   (
+       uuid uuid NOT NULL DEFAULT uuid_generate_v1(),
+       email text NOT NULL,
+       pass_hash varchar(512) NOT NULL,
+       CONSTRAINT users_pkey PRIMARY KEY (uuid)
+   );
+
+Example table content:
+
+====================================== ============= ==============================================================
+                 uuid                      email                               pass_hash
