To install the mod, unzip the files to a directory called Anarchy, under the Tribes directory.  Once done copy the Anarchy.cs file to the Config directory.  

You will need to edit the Anarchy.cs file to your liking, if questions about it post in the Forum .  Make sure that you change all the password entries.

Dedicated Server install:
Create a shortcut with the Infinite Spawn program located in the Tribes directory.  Once that is created right click on the shortcut and select properties.  In the line that reads Target make sure it looks like the below entry for a dedicated server.

C:\Dynamix\Tribes\infinitespawn *tribes.exe -mod Anarchy +exec Anarchy.cs +exec serverconfig.cs -dedicated

Hosting a game install:

Once you have completed the above start it up and enjoy :)
