Poky contains three metadata directories, meta, meta-poky, and meta-yocto-bsp, as well as a template metadata layer, meta-skeleton, which can be used as a base for new layers. Poky's three metadata directories are explained here:

• meta: This directory contains the OpenEmbedded-core metadata, which supports the ARM, ARM64, x86, x86-64, PowerPC, MIPS, and MIPS64 architectures and the QEMU emulated hardware. You can download it from its Git repository at http://git.openembedded.org/openembedded-core/.

Development discussions can be followed and contributed to by visiting the development mailing list at http://lists.openembedded.org/mailman/listinfo/openembedded-core.

• meta-poky: This contains Poky's distribution-specific metadata.
• meta-yocto-bsp: This contains metadata for the reference hardware boards.
