I'd just add: In today's market, in many/most location, you probably shouldn't sell unless you have a compelling need. (To my fellow Realtors: Yes, I know all markets are local, and some are doing quite well. And, yes, I'm aware that this may sound like a "doom and gloom, the sky is falling" response. It's not.)
I'm just suggesting that you really determine your own motivations and needs. And unless, on a scale of 1 to 10, they're at least an 8, and more often a 9 or higher, you really ought to scrutinize your initial impulse before deciding to sell.
It is a pretty broad question but, first things first; interview and hire a selling agent to market and sell your home. Now you do not have to hire an agent as I am sure you will here. I just suggest it if you are not well versed in the world of real estate. Check with the agents to see what their specific marketing plan for selling your home is, also confirm with them the method and frequency of the communication you would like to have from them, and of course carefully go over and make sure you totally understand the listing agreement should you choose to list your home with an agent.
This is just a very basic overview there are other items to consider such as offering a home warranty and maybe consider even going ahead and getting a home inspection to see if there are any issues ahead of time. So good luck whatever you decide.
