How do I settup keil to program NRF51?

[Sri_guy]

I want to make a blinky program from scratch and have no idea how to settup keil. I would prefer something step-by-step. I have been able to use the precompiled example, but never my own code and copying/pasting the code does not work.

Thanks

The answer would be extremely long. Needless to say it depends upon which version of the SDK you're using and which softdevice (and version) you're using.
