- Yocto Project A Linux Foundation project that acts as an umbrella for various efforts to improve Embedded Linux.
- OpenEmbedded The build system architecture promoted by the Yocto Project.
- BitBake A tool that reads metadata and runs tasks.
- OpenEmbedded-Core The common base set of metadata that BitBake uses. This metadata is shared between OpenEmbedded and the Yocto Project.
- Poky A reference distribution used for test and release purposes by the Yocto Project.

####Yocto Project Reference Manual
This manual provides reference information for the current release of the Yocto Project
- Using the Yocto Project Provides an overview of the components that make up the Yocto Project followed by information about debugging images created in the Yocto Project.
- A Closer Look at the Yocto Project Development Environment Provides a more detailed look at the Yocto Project development environment within the context of development.
- Technical Details Describes fundamental Yocto Project components as well as an explanation behind how the Yocto Project uses shared state (sstate) cache to speed build time.
- Migrating to a Newer Yocto Project Release Describes release-specific information that helps you move from one Yocto Project Release to another.
- Directory Structure Describes the Source Directory created either by unpacking a released Yocto Project tarball on your host development system, or by cloning the upstream Poky Git repository.
- Classes Describes the classes used in the Yocto Project.
- Tasks Describes the tasks defined by the OpenEmbedded build system.
- devtool Quick Reference Provides a quick reference for the devtool command.
- QA Error and Warning Messages Lists and describes QA warning and error messages.
- Images Describes the standard images that the Yocto Project supports.
- Features Describes mechanisms for creating distribution, machine, and image features during the build process using the OpenEmbedded build system.
- Variables Glossary Presents most variables used by the OpenEmbedded build system, which uses BitBake. Entries describe the function of the variable and how to apply them.
- Variable Context Provides variable locality or context.
- FAQ Provides answers for commonly asked questions in the Yocto Project development environment.
- Contributing to the Yocto Project Provides guidance on how you can contribute back to the Yocto Project.
===
- This quick start is written so that you can quickly get a build host set up to use the Yocto Project and then build some Linux images.
- Rather than go into great detail about the Yocto Project and its many capabilities, this quick start provides the minimal information you need to try out the Yocto Project using a supported Linux build host.
- Reading and using the quick start should result in you having a basic understanding of what the Yocto Project is and how to use some of its core components.
- You will also have worked through steps to produce two images: one that is suitable for emulation and one that boots on actual hardware.
- The examples highlight the ease with which you can use the Yocto Project to create images for multiple types of hardware.

####Getting Started with the Yocto Project - New Developer Screencast Tutorial
This half-hour screencast by Scott Garman introduces you to the Yocto Project and explains its benefits. It also includes live demos which explain the following:
- An overview of the Poky build system
- How the Poky sources are organized (types of metadata and where to find them)
- How to build your first Linux image and run it under emulation
- An introduction to recipes and an explanation of the most common types of metadata, using actual recipe examples
- An introduction to layers
- Where to obtain Yocto BSPs from
- How simple it is to download and enable a Yocto BSP
- Where to find further project resources (documentation, mailing lists, git repository, bugzilla)
By the end of this screencast, a new user will understand fundamental concepts about the build system, and be able to start their exploration of the Yocto Project with a solid foundation of knowledge.
