   5 This repository began as a GitHub fork of
   6 [joyent/node](https://github.com/joyent/node).
   7 io.js contributions, releases, and contributorship are under an
   8 [open governance model](./CONTRIBUTING.md#governance).
   9 We intend to land, with increasing regularity, releases which are
  10 compatible with the npm ecosystem that has been built to date for node.js.

  12 ### Is it io.js or IO.js or iojs or IOjs or iOjS?
  13
  14 The official name is **io.js**, which should never be capitalized,
  15 especially not at the start of a sentence, unless it is being
  16 displayed in a location that is customarily all-caps (such as
  17 the title of man pages.)
