 ## Background
-libp2p is a networking stack and library modularized out of [The IPFS Project](https://github.com/ipfs/ipfs), and bundled separately for other tools to use.
+libp2p is a [Peer-to-Peer](https://en.wikipedia.org/wiki/Peer-to-peer) networking stack, with [implementations](https://github.com/libp2p/libp2p#implementations) in multiple languages derived from the same [specifications.](https://github.com/libp2p/specs)

-libp2p is the product of a long and arduous quest of understanding; a deep dive into the internet's network stack and the peer-to-peer protocols from the past. Building large scale peer-to-peer systems has been complex and difficult in the last 15 years and libp2p is a way to fix that. It is a "network stack", a suite of networking protocols that cleanly separates concerns and enables sophisticated applications to only use the protocols they absolutely need, without giving up interoperability and upgradeability.
+Building large scale peer-to-peer systems has been complex and difficult in the last 15 years and libp2p is a way to fix that. It's striving to be a modular stack, with sane and secure defaults, useful protocols, while remain open and extensible.
+This implementation in native Nim, relying on [chronos](https://github.com/status-im/nim-chronos) for async. It's used in production by a few [projects](#users)

-libp2p grew out of IPFS, but it is built so that lots of people can use it, for lots of different projects.
