Most Nexus owners bought their device because they wanted a developer device that is super easy to unlock the bootloader and pretty much do whatever they want to their device. If you do own a developer device it is always nice to know how to do things like bootloader unlock and stock image flashing manually. However it can be time consuming to round up all of the necessary files, and if you aren't familiar with the processes you will be spending some time surfing the net trying to find the correct guides and tutorials for your particular device.
The SkipSoft Android Toolkit is the easiest way to Unlock, Root, and flash a custom Recovery to your Nexus device. The latest version of the toolkit has been released by developer "Mskip". The latest version of the toolkit includes support for the latest builds for all supported devices, updated superuser version, updated CWM recovery for the Nexus 5 to the official 6.0.4.5 version, added the information/help section to the model/build section screen to view information easier, added more text throughout the toolkit to clarify parts, and other minor bugfixes.
