Artifact is the simple, linkable and trackable design documentation tool for everybody. It allows anyone to write and link their design documents both to each other and to source code, making it easy to know how complete their project is. Documents are revision controllable, can be edited in the browser and have a full suite of command line tools for searching, displaying, checking, exporting and formatting them. Writing detailed design documents is one of the core pillars of quality software development. Design documents are how you capture the requirements (purpose) of your project and link them to your specifications (how you will build it). They let you get your ideas on paper before writing code, and help you have fewer painful refactors. They create a reference for developers and curious users of how and why your project was developed a certain way, and make it easier to refactor your project when that becomes necessary.
