 7 | ## What is this? ##
 8 | 
 9 | Use this script on your site to protest censorship of the Internet.  
10 | 
11 | After the page is loaded the script randomly censors text on the page by replacing the text with black bars.  It also places
12 | a black bar at the top of the page with a link to http://americancensorship.org/.  Viewers can remove censoring for the 
13 | current session by clicking on the "Remove this" link.
14 | 
15 | ## Example ##
16 | 
17 | Here is an example of Hacker News censored using the script:
18 | 
19 | [http://dougmart.in/stopcensorship/test.html][3]
20 | 
21 | ## Usage ##
22 | 
23 | First download script from here: [https://github.com/dougmartin/Stop-Censorship/zipball/master][4]
24 | 
25 | and then include the following script tag anywhere on your page:
26 | 
27 |     <script type="text/javascript" src="stopcensorship.js"></script>
28 | 
29 | You can alternativly include a version hosted on [cdnjs.com][5]:
30 | 
31 |     <script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/sopa/1.0/stopcensorship.js"></script>
32 | 
33 | ## Wordpress Plugin (new) ##
34 | 
35 | Christopher Davis created a Wordpress plugin to automatically add the script to your blog.  To use it just
36 | unzip the files into a new "stopcensorship" folder in your plugins folder and then activate it in your
37 | Wordpress admin.
