This should be cloned by default here:
C:\Users\{username}\AppData\Roaming\NCSOFT\WildStar\Addons\
To create an Addons folder and download everything (if you have installed Git) use following command:
git clone https://github.com/scscgit/scsc_wildstar_addons.git Addons
For an optional hourly auto-downloading of new version using Task Scheduler,
run the Schedule-Git-Auto-Refresh.bat. To improve your security, the
scheduled .vbs file to be run will be located above this Git directory.
Auto-download requires installed Git with command line integration (for git pull command).
