You need to have a custom Recovery on your phone if you want to install Custom ROMs. TWRP is such a popular Custom Recovery available for many devices including Galaxy Nexus.

DISCLAIMER:
Installing custom recovery on your device may VOID your warranty and may delete all your data. Before proceeding further you may consider backup of your all data. Understand the fact that you are the only person responsible for everything that you do with you device.

The complete process will be split into two parts as following:
– Unlocking the Bootloader
– Installing a custom recovery

Unlocking the Bootloader:

• Turn the phone off.
• Then boot it into the bootloader/fastboot mode by holding volume up + volume down + power.
• Open a command console and go to the directory where you have extracted adb and fastboot
  Type the following command in the console:

      $ fastboot devices

NOTE:
This command will list the connected devices.
If your phones serial number shows up you are good to go and may continue.
If the phone is NOT listed this indicates that your drivers are not installed correctly.
In order for you to continue you must configure your drivers properly so that your phone is listed under fastboot devices.

• If the phone has been recognized by the command above, proceed to unlocking the bootloader with the following command::

      $ fastboot oem unlock

NOTE:
Remember that this step will wipe EVERYTHING off the phone.
