Hi guys!
I have written two articles about Plutus that you might find interesting.
The first one is an attempt to summarise why Plutus, why did they bother inventing a new language that will target Cardano. The second goes through the first/easiest example of Plutus code available on the Plutus playground, which introduce the wallet API.
You can find these articles here: http://cardano-universe.com/plutus/
Have fun!
