How do you install a plugin on KSP?

[SemiaCloud]

I am on a mac 10.10 and am trying to install the procedural fairings plugin, it has a source code. Link:

I need help. The game still works but the stuff from the plugin is not showing up in the VAB or SPH.

There should be install instructions either on the PFairings thread or in the readme.

But, as a general rule, unzip the mod archive you downloaded, and match the folder structure they have from <KSP-root>/GameData/. If they include a GameData folder in their .zip, then put whatever is inside of their GameData folder in your GameData folder.

Once you've done it a few times, it'll be easy. Most mods use similar .zip file structure, so you'll notice patterns.
