Update blog to add a line on where to find demo materials

[oindrillac]

For a new reader of the blog, can we add a sentence after step 4 in steps to get you started on how to access the demo materials or what is the CTA, esp. for those who are not familiar with the repo structure, or know what to expect?

The instructions in the blog lead me to the entire repo:

As a step 5, can we add instructions to run a specific notebook from the notebooks directory which could serve as a demo/tutorial for the project?

Yeah, it makes sense.
I will add the steps.
