what version is this woocommerce tutorial for

Hi Suzanne, We actually have TWO WooCommerce courses. The newer of the two is our WooCommerce Quick Start, and it was just produced this past year. I believe that means it uses WooCommerce 3.4 or 3.5. The other course, our WooCommerce 101, is much more in-depth, and was recorded in 2017. We are working right now with the Automattic team to update and record a completely new series of video tutorials for WooCommerce 3.6. So, stay tuned for that. Hope this helps!
