Point to Alex's blog article instead of (or additionally to) book?

Starting to dig into DynamoDB at the moment and I came across this library. For someone new to DDB modeling, it isn't trivial to understand the "single table" concept.

The link to Alex Debrie's book in the Readme pointed me in the right direction, but after Googling I found out one of his blog posts explains the concept perfectly: https://www.alexdebrie.com/posts/dynamodb-one-to-many/ (concept 3 and 4). That means I can use this library without buying a book first (although I may do later), which I think would be valuable to others as well.

It's quite hard to understand this library's primitives without first reading the blog post I have to say (why two entities for one table, why "pk" and "sk" for naming etc.) so I would also suggest to place the link a bit more prominently.
