By default the Tuskfish home page displays a single combined stream of all content types. If you want to set up an index page with a specific type of content (eg. news articles, downloads, or images) take a look in trust_path/extras/type_specific_index_pages. There's one for every content type in there (eg. articles.php displays article content, only).

1. Drop the relevant file(s) you want to use into your site root (eg. articles.php).
2. Copy the matching .html template files (eg. articles.html) into the relevant theme directory.

They will just work.
