-    <para>This section is a stub, help us by expanding it</para>
+    <para>At this point, your <literal>$OEBASE/</literal> directory should
+      contain at least the following subdirectories:
+      <itemizedlist>
+        <listitem><simpara><literal>build/</literal></simpara></listitem>
+        <listitem><simpara><literal>bitbake/</literal></simpara></listitem>
+        <listitem><simpara><literal>openembedded/</literal></simpara></listitem>
+      </itemizedlist>
+    </para>
+
+    <section><title>Environment Setup</title>
+      <para>There are a few environment variables that you will need to set
+        before you can build software for OpenEmbedded using BitBake. You will
+        need to set these variables every time you open a terminal for
+        development. You can automate this in
+        <filename>~/.profile</filename>, <filename>/etc/profile</filename>, or
+        perhaps use a script to set the necessary variables for using BitBake.
+      </para>
+
+      <para>Since the path to your OpenEmbedded installation will be used in
+        many places, setting it in your environment will allow you to use
+        the <varname>$OEBASE</varname> variable in all pathes and make it
+        easier to change in the future should the need arise. To
+        set <varname>$OEBASE</varname> if you use a Bourne like shell
+        <footnote>
+          <para>If you use a CSH like shell (e.g. on a FreeBSD system), you
+            will set environment variables like this:
+            <screen>
+$ setenv VAR_NAME "VAR_VALUE"</screen>
+          </para>
+        </footnote>, do this:
+
+        <screen>
+$ export OEBASE=/path/to/your/oe/installation</screen>
+
+      </para>
+
+      <para>If you followed the recommendation to use BitBake from svn, you
+        will need to add the path to the BitBake executable to
+        your <varname>PATH</varname> environment variable like this:
+
+        <screen>
+$ export PATH=$OEBASE/bitbake/bin:$PATH</screen>
+      </para>
+
+      <para>In order for bitbake to find the configuration files for
+        OpenEmbedded, you will need to set the <varname>BBPATH</varname>
+        variable.
+
+        <screen>
+$ export BBPATH=$OEBASE/build:$OEBASE/openembedded</screen>
+      </para>
+
+      <para>Finally, if you wish to allow BitBake to inherit
+        the <varname>$OEBASE</varname> variable from the environment, you will
+        need to set the <varname>BB_ENV_EXTRAWHITE</varname> variable:
+
+        <screen>
+$ export BB_ENV_EXTRAWHITE="OEBASE"</screen>
+
+        Note the absence of the "$" character which implies that you are
+        setting <varname>BB_ENV_EXTRAWHITE</varname> to the variable name, not
+        the variable value.
+      </para>
+    </section>
+
+    <section><title>Local Configuration</title>
+      <para>It is now time to create your local configuration. While you could
+        copy the default <filename>local.conf.sample</filename> like this:
+
+        <screen>
+$ cd $OEBASE
+$ cp openembedded/conf/local.conf.sample build/conf/local.conf
+$ vi build/conf/local.conf</screen>
+
+        It is actually recommended to start smaller and
+        keep <filename>local.conf.sample</filename> in the background. Add
+        entries from there step-by-step as you understand and need
+        them. Please, do not just edit
+        <filename>build/conf/local.conf.sample</filename> but
+        actually <emphasis>READ</emphasis> it (read it and then edit it).
+      </para>
+
+      <para>For building an <literal>org.openembedded.dev</literal> branch, in
+        your <filename>local.conf</filename> file, you should have at least
+        the following three
+        entries: <varname>BBFILES</varname>, <varname>DISTRO</varname>
+        and <varname>MACHINE</varname>. For example, consider the following
+        mininal <literal>local.conf</literal> file for the &Aring;ngstr&ouml;m
+        distribution and the Openmoko gta01 machine:
+
+        <screen>
+BBFILES = "${OEBASE}/openembedded/packages/*/*.bb"
+DISTRO = "angstrom-2008.1"
+MACHINE = "om-gta01"</screen>
+      </para>
+    </section>
