I would like to know how to implement reset button on nRF51822. Image of schematic would be very useful, but good explanation should be enough. Thank you in advance.
I already have SWDIO/nRESET (pin 23) connected from ARM programming connector.

Hi,
You can connect a button from SWDIO/nRESET, which is active low (ie, tied to GND when pushed). When the MCU is in normal run mode, the SWDIO/nRESET pin can be used a normal reset input.
When you program the nRF-device, it will run in "debug mode" until you do a power cycle or do a pinreset from the debugger (cmd line: "nrfjprog --pinreset")
Best regards Håkon
