umm, its just putting it in c:/
*open it,
*start webserver,
*start sqlserver,
*start restarter,
then in restarter,
*start world
*start logon
then play
also you should take the ad.exe in tools,
put it in your world of warcraft dir, and make a empty folder there called maps,
then run ad.exe to extract the maps. when its finish, copy the maps folder
into your arcemu directory

maps is needed to make exploring maps + graveyards to work
Also if you want it public for all to connect,
*edit arcemu-realms.conf in the arcemu/config dir
and change the ip in bottom of config to your computer ip instead if 127.0.0.1.
If you have router, use a guide from mmowned guide section
in how to set up arcemu/ascent through router
