 <title>The Yocto Project Development Manual</title>
     <section id='dev-intro'>
         <title>Introduction</title>

         <para>
             Welcome to the Yocto Project Development Manual!
             This manual provides information on how to use the Yocto Project to
             develop embedded Linux images and user-space applications that
             run on targeted devices.
             The manual provides an overview of image, kernel, and
             user-space application development using the Yocto Project.
             Because much of the information in this manual is general, it
             contains many references to other sources where you can find more
             detail.
             For example, you can find detailed information on Git, repositories,
             and open source in general in many places on the Internet.
             Another example specific to the Yocto Project is how to quickly
             set up your host development system and build an image, which you
             find in the
             <ulink url='&YOCTO_DOCS_QS_URL;'>Yocto Project Quick Start</ulink>.
         </para>

         <para>
             The Yocto Project Development Manual does, however, provide
             guidance and examples on how to change the kernel source code,
             reconfigure the kernel, and develop an application using
             <filename>devtool</filename>.
         </para>

         <note>
             By default, using the Yocto Project creates a Poky distribution.
             However, you can create your own distribution by providing key
             <link linkend='metadata'>Metadata</link>.
             A good example is Angstrom, which has had a distribution
             based on the Yocto Project since its inception.
             Other examples include commercial distributions like
             <ulink url='https://www.yoctoproject.org/organization/wind-river-systems'>Wind River Linux</ulink>,
             <ulink url='https://www.yoctoproject.org/organization/mentor-graphics'>Mentor Embedded Linux</ulink>,
             <ulink url='https://www.yoctoproject.org/organization/enea-ab'>ENEA Linux</ulink>
             and <ulink url='https://www.yoctoproject.org/ecosystem/member-organizations'>others</ulink>.
             See the "<link linkend='creating-your-own-distribution'>Creating Your Own Distribution</link>"

	<title>The Yocto Project Development Manual</title>

	<title>Introduction</title>

	<para>
	Welcome to the Yocto Project Development Manual!
	This manual provides information on how to use the Yocto Project to
	develop embedded Linux images and user-space applications that
	run on targeted devices.
	The manual provides an overview of image, kernel, and
	user-space application development using the Yocto Project.
	Because much of the information in this manual is general, it
	contains many references to other sources where you can find more
	detail.
	For example, you can find detailed information on Git, repositories,
	and open source in general in many places on the Internet.
	Another example specific to the Yocto Project is how to quickly
	set up your host development system and build an image, which you
	find in the
	<ulink url='&YOCTO_DOCS_QS_URL;'>Yocto Project Quick Start</ulink>.
	</para>

	<para>
	The Yocto Project Development Manual does, however, provide
	guidance and examples on how to change the kernel source code,
	reconfigure the kernel, and develop an application using
	<filename>devtool</filename>.
	</para>

	<note>
	By default, using the Yocto Project creates a Poky distribution.
	However, you can create your own distribution by providing key
	<link linkend='metadata'>Metadata</link>.
	A good example is Angstrom, which has had a distribution
	based on the Yocto Project since its inception.
	Other examples include commercial distributions like
