To get started fast:
run forge - located in $FORGE_HOME/bin/
localhost:~ $ forge
[~] $

If you have not yet seen the Forge built-in commands, you may either press TAB to see a list of the currently available commands, or get a more descriptive list by typing:

$ command-list

Then to get started - see the docs at
https://forge.jboss.org/documentation 
Consider installing Git and Maven 3.1+ (both optional)

Restart Terminal to use forge.
