Normally, you d/l the mod and then unzip it into the standard install path for BTS. In the case of a
normal retail version of BTS using XP, the path looks like this:
If you are using Vista, the path looks like this:
In both cases, the mod goes into the
MODS folder. Also, on Vista the Appdata folder is hidden. You will have to unhide it to be able to easily unzip the mod into it. See the individual folders under the mods folders in the examples? Those are individual installed mods.
Note that the install paths for D2D and Steam versions, and Civ Complete or the Gold edition
are not the same. You're on your own there, sorry.
Some mods have an installer built into them, like Varietas Delectat, Rise of Mankind, and the previously mentioned, and excellent, Legends of Revolution. For those, it's a simple matter of running an install program.
Good luck.
