VPN setup on rb950

Hi,
I am using a mikrotik router to manage my network and I would wish to access my router remotely eg from home or public network to access services on the router and do configurations.
Currently I am using the default mikrotik configuration settings . please assist on the steps I need to take to configure VPN on the router and VPN on my android device and also any other settings that I need to edit in the firewall on the router .
Regards
