How to jailbreak an iPhone 5c on IOS 7.1.1?

I want to know how to jailbreak my iPhone 5c in blue on IOS 7.1.1. I want to do it via my computer or an app, I don't want to have to take it to someone.
And also, will it be a quick process or will it take a few days and also what are the pro's and con's about jail breaking.

Its highly unlikely that your device will break down as jailbreak is nothig major and I have never faced any issue use EVASION Jaibreak http://evasion7.com/iOS7.1.1_jailbreak

DON'T. JUST DON'T. When some people jailbreak their devices it works, but there's a good chance that your phone will totally breakdown and stop working. It happens. There are a lot of tutorials on how to jailbreak your phone on youtube.com but i highly suggest you do NOT because if your phone does break down, Apple won't do anything to fix it, you'll just have to buy a new one. And that's a waste… Just deal with Apples regulations.
