Please I some need with Bootstrap and jQuery

Good Day everyone! (anyone!). I have been trying to use bootstrap and jQuery on my personal editor (sublime text) with the link that was given on the Bootstrap tutorial and it has refused to work.

Please how do I start using Bootstrap and jQuery on my editor?

Thanks in advance.

Can you put your code in a CodePen or JSFiddle? This will help us debug.
