Welcome to the Yocto Project Concepts Manual! This manual provides conceptual information that helps you better understand the Yocto Project. You can learn about Yocto Project components, cross-development toolchain generation, shared-state cache, and many other concepts. This manual does not give you the following: Complete Step-by-step Instructions for Development Tasks: Instructional procedures reside in other manuals within the Yocto Project documentation set. For example, the Yocto Project Development Tasks Manual provides examples on how to perform various development tasks. As another example, the Yocto Project Application Development and the Extensible Software Development Kit (eSDK) manual contains detailed instructions on how to install an SDK, which is used to develop applications for target hardware. Reference Material: This type of material resides in an appropriate reference manual. For example, system variables are documented in the Yocto Project Reference Manual. As another example, the Yocto Project Board Support Package (BSP) Developer's Guide contains reference information on BSPs. Getting Started Material: This type of material resides in the Getting Started With Yocto Project Manual. Detailed Public Information Not Specific to the Yocto Project: For example, exhaustive information on how to use Git is better covered with Internet searches and official Git Documentation than through the Yocto Project documentation.

Because this manual presents information for many different concepts, supplemental information is recommended for full comprehension. For additional introductory information on the Yocto Project, see the Yocto Project Website. You can find an introductory to using the Yocto Project by working through the Yocto Project Quick Start. For a comprehensive list of links and other documentation, see the "Links and Related Documentation" section in the Yocto Project Reference Manual.
