hi, found your profile from @bien, welcome to steem. You have a little bit of STEEM in your wallet, use it to power up so you have more RCs

I have a course on udemy you can take for free that might help you understand the process

sign up for the course and if you are still having RC problems let me know and we can have a chat :-)
