impress.js is a presentation framework written in JavaScript that uses the power of CSS3 transitions and transforms. It is inspired by the idea behind prezi.com
**WARNING**
impress.js may not help you if you have nothing interesting to say ;)
***THIS VERSION IS UNSTABLE AND INCOMPLETE. Please use the [upstream version](https://github.com/impress/impress.js) (V2.0.0)!***
A rewrite of this README file is also ongoing, therefore it also contains comments and some unfinished sections, as well as the fact that it looks kinda awful with the partial changes that I have made so far.
We are also switching to TS as the main impress development language, but you can still develop plugins in JS, if you wish!
# Getting Started with impress.js
Welcome to impress.js, the impressive JavaScript framework, that allows you to build presentations for web browsers.
## Browser support
Since impress.js is designed to show of the power of modern CSS, we cannot guarantee that it will run in older browser. Whilst we try not to intentionally not support browsers, some features might not work well on all browsers, especially with V3.x. For example, Internet Explorer is known to not work with V3.x, so if you really NEED to use that browser, please use V2.x. impress.js works best with the latest versions of Chrome, Firefox and most likely also with the latest versions of Safari.
## Quick Start
You can visit our website at [https://impress.js.org](https://impress.js.org) to learn more about the project, where you can also find helpful resources for getting started, like the [Getting Started Guide](/docs/GettingStarted.md) and [Documentation](/docs/DOCUMENTATION.md), but rendered as HTML instead of MarkDown, as it is here on GitHub.
## A very quick quick start
Copy one of the code snippets below to the header of your impress.js presentation's HTML file.
- V3.0.0:
```
```
- V1.1.0:
```
```
- Upstream:
```
js/impress.js`, and testing, `impress.js` itself doesn't depend on Node or any NPM modules.
# About impress.js
## ABOUT THE NAME
impress.js name is [courtesy of @skuzniak](http://twitter.com/skuzniak/status/143627215165333504).
It's an (un)fortunate coincidence that an Open/LibreOffice presentation tool is called Impress ;)
