+Setup PostgreSQL access
+=======================
+
+Libeufin connects to a PostgreSQL instance via TCP.  In
+order to keep the development light, the password authentication
+should be disabled on the local machine.
+
+The first step is to (1) locate the file pg_hba.conf.  In
+debian systems, this is usually located under "/etc/postgresql/$VERSION/main/".
+
+Then (2) add the following rules to it:
+
+    # allows libeufin to connect password-less.  NOTE: it might be
+    # important to keep the following two lines before the third line
+    # showed in this snippet.
+    
+    host   libeufintestdb         libeufin   127.0.0.1/32          trust
+    host   libeufindb             libeufin   127.0.0.1/32          trust
+    # IPv4 local connections:
+    host    all             all             127.0.0.1/32            md5
+
+(3) Create the databases "libeufintestdb" and "libeufindb"
+(4) Create the role "libeufin"
+(5) Restart the database
+
+If the configuration was successful, the following command should
+access the "libeufin" database without asking for a password:
+
+    $ psql -U libeufin -h 127.0.0.1 -d libeufindb
+
+If 'psql' could not find the right port to connect, consider using
+the "-p $PG_PORT" option.
+
 Launching LibEuFin
 ==================
 
-All the three commands can be launched with the "--help"
-option, and show how they can be invoked!
+Try the command
+
+    $ libeufin-$SERVICE
+
+where SERVICE equals either 'nexus' or 'sandbox'.
