Using custom files in Ruby/scripts to create working wc3 map - ruby

Question

I am totally green in those kind of things, I tried reading some tutorials and still couldn't do it on my own.
Here lies the problem: I have 2 files (bulid, compile) which are somehow supposed to take other files and create a working warcraft3 map.
There's an instruction I followed:
To build:_
$ ./scripts/compile # most basic way of calling compile
$ ./scripts/build # most basic way of building a map
build
Script which takes an unportected map and applies any build settings passed via argv
upon on it then turns it into a working warcraft3 map file.
Options | Default | Description
----------------|-------------------------|---------------------------------------------------------------------
env | beta | map environment: each environment has default build settings
debug_script | false | debug this build script
do_jasshelper | true | turns vJass & ZINC into JASS
do_compile | true | turns ../src into out.j. When false, looks for {map_script_path}
do_optimizer | false | uses Vexorian's map optimizer to protect and make the map run faser
do_widgetizer | false | uses PitzerMike's map widgetizer to make map load faster
debug | false | whether the --debug flag should be passed to jasshelper
launchwc3 | false | whether the script should launch wc3 with the map loaded on exit
map_unpro_path | base-maps/{highest}.w3x | the base map file to inject script into
map_script_path | ../out.j | map script path to load into map
map_output_path | ITT_{commit}_{time}.w3x | path where to put the compiled map
setting up
This application requires Ruby
$ git clone git#github.com:theQuazz/island-troll-tribes
$ cd island-troll-tribes
$ scripts/build
It might be a easy thing to do, but I am really bad at this kind of stuff, if someone could explain what to do step by step I would greatly appreciate it
