Content tutorial and using portfolio function to organise text-based articles

Hello. I just read the first two numbered tutorials on how to set up Pinboard and found them very helpful and well written. The last tutorial mentions that number 3 will be on formatting post content. Is this available?

I’m using a static home page with a grid layout (or will be, when its configured) and I plan to upload numerous sequential articles (reviews of TV series, etc.) in a dedicated review section of the site. Because of the way these articles must relate to each other I was wondering if they could be organised as though they were a portfolio. Does anyone have any suggestions as to whether this is practical?

Thanks
