+You came to the correct place, this
+document will guide in the process of
+deploying a development version of
+this project.
+
+## Installing
+
+This guide is centered on Debian 12, if 
+you are using a different OS and do
+not know how to continue ask us.
+
+### Postgresql notes.
+
+We are going to use the peer authentication that
+comes preconfigured in Debian, if you are using
+other OS you should care of `pg_hba.conf` to
+be configured as peer for empty address.
+
+This is how it looks on the Debian I used.
+
+You can also configure it with password if the database
+server is not the same host that the webserver, it
+is supported by the software.
+
+```
+local   all             postgres                                peer
+
+# TYPE  DATABASE        USER            ADDRESS                 METHOD
+
+# "local" is for Unix domain socket connections only
+local   all             all                                     peer
+# IPv4 local connections:
+host    all             all             127.0.0.1/32            scram-sha-256
+# IPv6 local connections:
+host    all             all             ::1/128                 scram-sha-256
+# Allow replication connections from localhost, by a user with the
+# replication privilege.
+local   replication     all                                     peer
