Best way to install addon

I’m trying to install the gear addon. I went to http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Add_Mesh/Add_Gear for the current version, but I’ve never downloaded a .py file before. What would I need to do in order to download and install the Addon (I have Windows 8)

Thanks

Hi, if you are using a newer version of blender this add-on is already implemented.
Go to User Preferences —> Add Mesh: Extra Objects —> activate

Now in the viewport click Shift + A --> Mesh --> Gears

And don’t forget to save your user preferences, if you change something.

Generally speaking you can download a python script (add-on) and copy it in your …/blender-2.76/2.76/scripts/addons folder, activate it, done.
