To add a new episode to a TV show, look up the series title in the database, scroll through the main cast/credits, and click on the 'Add episode' button in the 'Contribute to this Page' section at the bottom of the page.
Fill in the required information, click on 'Continue' and follow the on-screen instructions.
You'll see a section on the page called 'Recommended Information' - allowing you to add credits for the episode you're adding (e.g. the name of the director, writers etc.)
To add the names of the actors who starred in that episode (incl. guest appearances), select 'Add X credits' next to the 'Cast' option (where 'X' is the number of credits you want to add).
