+<title>Requirements</title>
+<para>
+We need the tools to build a module and a building linux tree. Running the built
+linux kernel is highly recommended so we can test our modules.
+</para>
+<para>
+The tools include GNU make, GCC and GNU binutils. Linux build is highly
+dependent on the GNU toolchain, since the beginning.

+<para>
We have prepared sample code to build in the samples/ directory. Try them.

+<title>Init and Exit Functions</title>
+<para>
+We use <emphasis>module_init</emphasis> and <emphasis>module_exit</emphasis> to
+declare our init and exit functions.

+<title>Init and Exit Functions</title>
+<para>
+The <emphasis>__init</emphasis> and <emphasis>__exit</emphasis> marks allow the
+kernel to remove them when they are not needed, reducing memory consumption.
