+This repository implements BitTorrent-related packages and command-line utilities in Go. The emphasis is on use as a library from other projects. It's been used 24/7 in production by a downstream, private service since late 2014. There have been contributions from people using some various packages for integrating BitTorrent into media and other services.
 
-There is support for protocol encryption, DHT, PEX, uTP, and various extensions. There are several storage backends provided, blob, file, mmap. You can use the provided binaries in `./cmd`, or use `torrent` as a library for your own applications.
+There is support for protocol encryption, DHT, PEX, uTP, and various extensions. See the package documentation for a more complete list. There are several data storage backends provided: blob, file, and mmap, and you can write your own, such as to store data on S3, or in a database. You can use the provided binaries in `./cmd`, or use `torrent` as a library for your own applications.
