I have created altcoin from Bitcoin source code. I would like to list this, but I would like to know the specific steps. Please give me some sources of information.
You had better get connected with support team of an exchange you want your token to be listed. Every exchange has its rules, they will check if you meet all requirements and also you will have to pay a fee.
So that your token will be successful, you had batter run a marketing campaign such as advertisement and build a loyal community.
