+> ### For Parsing DTS From Stock DTB :
+                                ./dts.sh markw Image.gz-dtb
+				markw = my device name here
+			        Image.gz-dtb = my kernel name in this directory!
+
+> ### For comparing Defconfigs :
+                                 python compare_defconfig.py mido_defconfig mido1_defconfig > Difference.txt
+				 mido_defconfig & mido1_defconfig = name of defconfig to compare!
+				 Difference.txt = Difference between two defconfig!
+
+> ### For Repacking ( boot.img & recovery.img ) : 
+                                 python repack_images.py stock.img folderwithkernels/
