-#### Update submodules
-```
 # Update submodules branches after they got updated 
 git submodule update --remote
+
+# Fetch and pull from submodules repositories
+git submodule update --init --recursive --remote

+### Adding a Driver
+### Add Driver
+
+In order to add a Driver you would follow this procedure, where you add the the dtbs Makefiles to the DTB_LIST and the Driver Makefile to the KERNEL_OVERLAY variable. Refer to the following example:
+
+
+```
+> vi kernel/kernel-4.9/arch/arm64/boot/dts/Makefile
+
+Add the following content before `DTB_LIST += $(dtb-y)`:
+
+######### Include RidgeRun #########
