 This is the server side for [SP7-Ritmare/EDI-NG_client](https://github.com/SP7-Ritmare/EDI-NG_client).
 
 It's a [Spring](http://spring.io) Boot application configured to package as a WAR file, so as to allow deployment to, e.g., [Tomcat](http://tomcat.apache.org).
+In order to deploy to Tomcat, you need to place the WAR file in Tomcat's webapps directory, or upload it via the Tomcat manager application.
 
 [Binary WAR file](https://github.com/SP7-Ritmare/EDI-NG_server/releases/download/v1.0/edi.war) is available via the "releases" tab.
-
 The WAR has been tested on Tomcat 7.
 
+> You will probably not need the pre-packaged WAR, anyway, because it points to our own installation of the PostgreSQL database.
+> You should edit your copy (https://github.com/SP7-Ritmare/EDI-NG_server/blob/master/EDI-T/src/main/resources/application.properties) file and change the spring.datasource.* entries to point to your own PostgreSQL installation.
+> **Warning**: deploying the WAR file will create all necessary tables, but it WILL NOT create the database.
+
+If you want to build the latest release from sources, you can user [Apache Maven](https://maven.apache.org/index.html) (Apache License v2.0). In the EDI-T directory, simply run:
+```bash
+mvn package
+```
+This will create your WAR file in the target directory, ready for deployment.
