## Getting started
**Online demo**
### Online demo
For an online demo, visit:
http://andreasgal.github.com/pdf.js/web/viewer.html
+ http://andreasgal.github.com/pdf.js/web/viewer.html
This demo provides an interactive interface for displaying and browsing PDFs
using the pdf.js API.
**Getting the code**
### Getting the code
To get a local copy of the current code, clone it using git:
```bash
git clone git://github.com/andreasgal/pdf.js.git pdfjs
cd pdfjs
```
$ git clone git://github.com/andreasgal/pdf.js.git pdfjs
$ cd pdfjs
Next, you need to start a local web server as some browsers don't allow opening
PDF files for a file:// url:
```bash
make server
```
$ make server
If everything worked out, you can now serve
http://localhost:8888/web/viewer.html
+ http://localhost:8888/web/viewer.html
You can also view all the test pdf files on the right side serving
