 No Flash, No Java, No Websocket, No Bullshit.
 
 
-This is a very small (4k) Speedtest implemented in Javascript, that relies only on XMLHttpRequest.
 
+This is a very small (4k) Speedtest implemented in Javascript, using XMLHttpRequest and Web Workers.
 
 
 ## Try it
 
 [Take a Speedtest](http://speedtest.adolfintel.com)
 
 
 ## Compatibility
 
-Microsoft Edge, Firefox 10+, Chrome 10+, Opera 15+, Safari 7 (not tested)
 
+Only modern browsers are supported (Edge 12+)
 
 
 ## Requirements
 
- - A reasonably fast web serve
 
+ - A reasonably fast web server
 
  - Some way to generate garbage data using either the included PHP script, a [big file of random data](http://downloads.adolfintel.com/geth.php?r=speedtest-bigfile), or a symlink to /dev/urandom
 
  - Your server must not compress the data it sends
 
  - Your server must accept large POST requests (up to 10 Megabytes), otherwise the upload test will fail
 
  - Client side, there must not be any type of buffering (such as a proxy), or you may get incorrect results
 
 
 ## How to use
 
-See example.html, it's not rocket science.
 
+See the examples, it's really simple.
