Poky is the Yocto Project reference distribution. It contains the Open-Embedded build system (BitBake and OE-Core) as well as a set of metadata to get you started building your own distribution. See the figure in "What is the Yocto Project?" section for an illustration that shows Poky and its relationship with other parts of the Yocto Project.
To use the Yocto Project tools and components, you
can download (clone
) Poky and use it
to bootstrap your own distribution.
You can read more about Poky in the "Reference Embedded Distribution (Poky)" section.
