This template can be used via substitution to start a new episode article.
Prerequisites
Before you begin, make sure that the episode you want to create an article for has an entry in Module:EpisodeData. The entry must at minimum have a "name" and an "airdate".
Creating a new episode article
Go to List of Episodes and click on the red link for the new episode. Use the source code editor to enter this code into the page:
{{subst:New episode|chain|15}}
where "chain" is the show's code from Module:EpisodeData and "15" is the number of the episode. Save the page and a new episode article will be created.
