## How to install

*Smart Duplication* is installed [like any regular *Blender* addon](https://docs.blender.org/manual/en/latest/editors/preferences/addons.html#rd-party-add-ons).

It's meant to work on any OS that *Blender* supports (*Windows*, *Mac* and *Linux*) and requires at least *Blender 2.80* or a newer version.
