Use 7zip to extract the zip into your TurtleWoW/Interface/AddOns/ folder.Visit the github link you find, then click the green Code button, and select Download ZIP.If that is okay with you, learn this installation process: This method is simple, and works with any addon you find, even ones that don't use git, but the downside is that there's no easy way to update all your addons at once.
How to Install Addons Installing Addons by Hand WeakAuras DOES NOT EXIST for Turtle WoW! While it is a shame that you lose the convenient form factor of WAs, you can still accomplish almost everything WAs could do by using full addons instead. It is still a modified 1.12 client and cannot use Classic addons.) (And yes, the above holds true even though Turtle WoW reports itself as 1.16, 1.17, or higher. This page intends to always list the correct version that you should use. Addons here are a mix of Vanilla 1.12 addons from 2006, newer pserver-era 1.12 addons, and versions of addons updated specifically to work correctly on Turtle. As such, Classic addons (1.13/1.14) DO NOT WORK! If you are coming from Classic, clear your mental slate and be prepared to find a completely new set of addons to accomplish what you want. Turtle WoW is a mod on the 2006 version of the game, using the 1.12 client.
