Introduction
Introduction This manual provides reference information for the current release of the Yocto Project. The Yocto Project is an open-source collaboration project focused on embedded Linux developers. Amongst other things, the Yocto Project uses the Poky build tool to construct complete Linux images. You can find complete introductory and getting started information on the Yocto Project by reading the Yocto Project Quick Start. You can also find lots of information on the Yocto Project on the Yocto Project website.

System Requirements For system Yocto Project system requirements, see the What You Need and How You Get It section in the Yocto Project Quick Start.
Obtaining the Yocto Project The Yocto Project development team makes the Yocto Project available through a number of methods: Releases: Stable, tested releases are available through . Nightly Builds: These releases are available at . These builds include Yocto Project releases, meta-toolchain tarballs, and experimental builds. Yocto Project Website: You can find releases of the Yocto Project and supported BSPs at the Yocto Project website. Along with these downloads, you can find lots of other information at this site.
Development Checkouts Development using the Yocto Project requires a local copy of the Yocto Project files. You can get these files by downloading a Yocto Project release tarball and unpacking it, or by establishing a Git repository of the files. For information on both these methods, see Getting Setup section in The Yocto Project Development Manual.
