<title>Getting Ready to Develop using <filename>devtool</filename></title>
<para role='writernotes'>
Need the updated wiki stuff here
Sections as follows:
<orderedlist>
<listitem><para role='writernotes'>
Source the oe-init-build-env script.
At this point, we assume the build host is set up and
<filename>poky</filename> repository has been cloned.
</para></listitem>
<listitem><para role='writernotes'>
Be sure your <filename>local.conf</filename> file has
the correct
<ulink url='&YOCTO_DOCS_REF_URL;#var-MACHINE'><filename>MACHINE</filename></ulink>
variable set for the target hardware on which your
kernel image runs.
Also have the
<ulink url='&YOCTO_DOCS_REF_URL;#var-MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS'><filename>MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS</filename></ulink>
variable set equal to "kernel-modules".
</para></listitem>
<listitem><para role='writernotes'>
Create a layer for later that will contain your patches
(if any) to the kernel.
</para></listitem>
<listitem><para role='writernotes'>
Build the extensible SDK.
</para></listitem>
<listitem><para role='writernotes'>
Install the extensible SDK.
</para></listitem>
<listitem><para role='writernotes'>
Set up the terminal so that you can work with the
extensible SDK.
This terminal is known as the "eSDK Terminal" unlike the
terminal that is set up to run BitBake, which is known
as the "BitBake Terminal".
</para></listitem>
<listitem><para role='writernotes'>
Build the initial image using the extensible SDK.
</para></listitem>
</orderedlist>
</para>
<para role='writernotes'>
At this point, the user has enough stuff set up to work on the
kernel.
I will put a section in the "Common Tasks" area of this manual
that finished out how to make a modification to the kernel.
