 # Fimfarchive
 
-Fimfarchive preserves stories from Fimfiction.
+Fimfarchive aims to release all stories on Fimfiction as a single ZIP-file. The
+archive contains not only stories, but also metadata such as tags, ratings, and
+descriptions. It is organized by author and could be used for backup, offline
+reading, or data mining.
+
+Releases can be found on Fimfarchive's [user profile] at [Fimfiction]. Note
+that this is **not** an official Fimfiction project, so do not send questions
+to Fimfiction staff. Instead, send a private message or post a comment to the
+Fimfarchive user profile.
+
+A new version will be released each season via BitTorrent, approximately once
+every three months. When suitable, an xdelta3 patch will also be provided for
+users who do not wish to redownload unchanged stories.
+
+Note that the archive contains a large number of files. Unzipping it to your
+file system may not be necessary if the archive is to be used together with
+some application. If you are a developer, reading directly from the ZIP-file
+may be preferable.
+
+This repository contains the code for updating and building the archive. While
+the API is not guaranteed to be stable, it can also be used as a library for
+easy access to stories and metadata within the archive.
