HOW TO USE IT
---------------
[Use the source](http://github.com/bartaz/impress.js/blob/master/index.html), Luke ;)
If you have no idea what I mean by that, or you just clicked that link above and got
very confused by all these strange characters that got displayed on your screen,
it's a sign, that impress.js is not for you.
Sorry.
Fortunately there are some guys on GitHub that got quite excited with the idea of building
editing tool for impress.js. Let's hope they will manage to do it.

So you'd like to know how to use impress.js?
You've made the first, very important step -- you're reading the source code.
And that's how impress.js presentations are built -- with HTML and CSS code.
Believe me, you need quite decent HTML and CSS skills to be able to use impress.js effectively.
And what is even more important, you need to be a designer, too, because there are no default
styles for impress.js presentations, there is no default or automatic layout for them.
You need to design and build it by hand.
So...
Would you still like to know how to use impress.js?

You can also use `#step-2` in a link, to point directly to this particular step.
Please note, that while `#/step-2` (with slash) would also work in a link it's not recommended.
Using classic `id`-based links like `#step-2` makes these links usable also in fallback mode.

Now you know more or less everything you need to build your first impress.js presentation, but before
you start...
Oh, you've already cloned the code from GitHub?
You have it open in text editor?
Stop right there!
That's not how you create awesome presentations. This is only a code. Implementation of the idea that
first needs to grow in your mind.
So if you want to build great presentation take a pencil and piece of paper. And turn off the computer.
Sketch, draw and write. Brainstorm your ideas on a paper. Try to build a mind-map of what you'd like
to present. It will get you closer and closer to the layout you'll build later with impress.js.
Get back to the code only when you have your presentation ready on a paper. It doesn't make sense to do
it earlier, because you'll only waste your time fighting with positioning of useless points.
If you think I'm crazy, please put your hands on a book called "Presentation Zen". It's all about
creating awesome and engaging presentations.
Think about it. 'Cause impress.js may not help you, if you have nothing interesting to say.
