# Welcome to the IPFS docs

The InterPlanetary File System (IPFS) is a set of composable, peer-to-peer protocols for addressing, routing, and transferring content-addressed data in a decentralized file system. Many popular Web3 projects are built on IPFS - see the ecosystem directory (opens new window) for a list of some of these projects.
