+How to compile jordan kernel modules
+------------------------------------
+
+These external kernel modules require the Defy kernel tree :
+
+It is available at https://github.com/CyanogenDefy/kernel-omap
+
+Add to your repo manifest \<project path="kernel" name="CyanogenDefy/kernel-omap" />
+
+---
+
+"repo sync" and then, in root of your android repo :
+
+    . build/envsetup.sh
+    lunch cyanogen_jordan-eng
+
+    make kernel
+    make jordan_modules
+
+---
+
+PS : Do not make menuconfig, or use make in kernel tree, if you have an error reporting
+the kernel source is not clean, type before :
+
+    make kernel_clean
+
