The home page is your task list and the place you start new work.
New
The composer. See The composer.
Tasks
Everything currently running or waiting on you. A task shows what it is doing and, when it needs an answer, says so here.
Archive
Finished tasks. The work stays in the directory; this is just your list.
Claims
Statements the work is relying on that are waiting for your confirmation. A count appears when there are any. See Claims.
Dossier examples
Worked examples of what finished output looks like, useful before you have run much yourself.
Ordering
Tasks are ordered by when you created them, newest first.
