Confused with installation

Hi, I apologize for such a noob question. I’m currently on Ubuntu 20.04, with GTX 1070Ti. I am following Part 1 (2020) and I was confused with the different versions of installation, particularly this. So i take a look in the coursev3 url and found that it wasn’t the latest version, so i headed to here. So how do I clone this latest version of fastai? By replacing the git clone code in step 3 of this with this (GitHub - fastai/fastbook: The fastai book, published as Jupyter Notebooks) ?

Any help would be greatly appreciated.

Problem solved.
