how to hack minecraft?

i cannot open the hack i download? (Executable jar file)
someone can teach me or give the links to the tutorials? i am a newbie here...

download a hacked client

take the downloaded file and paste it into your versions file inside the .minecraft folder

make sure that when you open the downloaded file, it contains only a .jar and .json file of the same name

open the launcer and click edit profile

select the version that matches the name of your hackpack

launch minecraft

my description is rather hard to follow im sure. youd be better off looking up a youtube video of how to do it
