installing offset edges addon

I would like to use the Offset Edges addon, the user manual says that it’s an edge tool, but it’s not in my list of add ons.

From the link in the manual I found myself here:

But I don’t know what to do with all that code. How do I install this? Is there a link I’m missing, or am I expected to know what to do with the code?


Save the .py file and in the User Preferences / addons use the ‘Install from File’ button. Select the .py file and enable it with the addon tickbox.

Okay, got it. Thank you.
