First Time Jailbreaking Need Help

Hi so to make a long story short a friend of mine gave me his old ipad gen 1. As I'm sure some of you know, Apple products have a safety measure on them called an Activation Lock. This calls for the users apple Id and password which my friend does not remember. So I went and found this software called aiseesoft iphone unlocker which gives me the option to delete the apple id from the ipad itself but in order to do that I have to jailbreak the ipad which I have no clue how to do. I would really really appreciate it if someone could help me out.
