Clarify tag flashing

[skorokithakis]

Hello! I got the recommended nrf51 tags from Ali, and now I'm trying to flash them. However, the docs are a bit hazy. I know I should replace PREFIX_keyfile with the keyfile, but I'm not sure if I should replace OFFLINEFINDINGPUBLICKEYHERE with anything, or if that's a literal that's supposed to be in the firmware itself. If I need to replace this with the advertisement key, what format should that key be in?

Could the documentation please be clarified with which strings should be replaced with what?

OFFLINEFINDINGPUBLICKEYHERE is a marker for the beginning of the "memory area" containing keys. The keys from the _keyfile (except the first byte) are dumped directly into the bin file before flashing.

You don't have to change OFFLINEFINDINGPUBLICKEYHERE.

Thanks, I've opened #136 for this.
