And search this forum for same process with UNO, MEGA, etc…
Read through them ALL… Please do NOT ask for help in those topics!! You have you own topic here… and shouldn’t need any more info then what you will find by simply reading 
This is an overly well documented thing. Absolutely no need for yet another “How too” topic on this device merger
