I'm complete newbie here, can anyone help me how to do CPFP or RBF? I want my transaction to be completed as soon as possible.
Thanks in advance for help.
Depends on the wallet you are using, it will either have it implemented or not.
For electrum there's dozens of guides available, -- simply google. This one for example :
RBF:
