Setting up a Pi 4 for video

First time user of a Pi. I want to use to to watch netflix and Stan in the man cave (so the lappy can go back to actual work stuff)
I set the wee beast up fine but when I tried to run anything from either site it says I need to install apps and HTML 5. I tried looking for these and failed miserably (Its also slightly too technical and swearing at it hasn’t worked)
Could you kind and knowledgeable chaps point me in the right direction please?

Hi Steve,

Welcome to the world of Raspberry Pi, A good place to start with this would be to have a look for a guide, I found this one on how to set up Netflix. If you run into any trouble let us know.
