ClockworkMod also known as CWM is one of the most popular custom recoveries for all android devices. Custom recoveries in general helps you perform some more advanced functions such as full backup of your rom which is also known as nandroid backup and also restore, it also helps you install both signed and unsigned zip updates, themes, kernels etc.
Though all android devices comes with stock recovery but they only perform some few operations like installation of official zip update, factory reset etc. That’s the importance of custom recovery. It over writes the stock recovery and also help you perform some additional functions which you can’t find in the stock recovery.
There are different ways of booting into recovery. You can either boot from startup by pressing together the volume down and power button or volume up and power button, depending on the device.
You can also boot into recovery with rom manager or mobile uncle for mtk devices.

2. Install zip from sdcard: This is where the installation of all flashable zip files take place.it also has some submenus which are:
