Installation

Assuming you have PHP installed, the installation steps are quite simple. I set this up on a QNAP. For this example, I am using a folder called speedtest in my web share area.

1. Choose one of the example-xxx.html files in examples folder as your index.html if the default index.html does not fit.
2. Add: speedtest.js, speedtest_worker.js, and favicon.ico to your speedtest folder.
3. Download all of the backend folder into speedtest/backend.
4. Download all of the results folder into speedtest/results.
5. Be sure your permissions allow execute (755).
6. Visit YOURSITE/speedtest/index.html and voila!
