How do I add a description to an individual episode

Hi, and I’ve noticed that some episodes each have their own description and I would like to know how to add a description to each episode. If anybody knows, then please let me know.

In your portal next to each episode from episode 2 and up, there should be something like a hyperlink in blue that says “add”. It only says “change” for me bc I already added one : )

And then you can change it :yum:
