HSEARCH-1644

Docs updates ! :-)

Initially I suggested to just make this section a note (aka [NOTE]).

With the dependency section I meant introducing a new section after 'system requirements':

    1.1. System Requirements
    1.2 Required dependencies 
       1.2.1 Using Maven
       1.2.2 Other
    1.3. Deploying on WildFly
