 ## How it works
 
-The tool is based on the fabulous [Phantomas](https://github.com/macbre/phantomas) by Maciej Brencz, that loads a page and collects many web performance metrics.
-I rewrote some modules to deeper analyze Javascript interactions with the DOM (especially with jQuery).
-And then it is wrapped inside a small NodeJS server to get an interface (inspired by my favorite tool: [WebPageTest](http://www.webpagetest.org/)).
+The tool loads the given URL and collects various metrics and statistics with the help of [Phantomas](https://github.com/macbre/phantomas). These metrics are then categorized and transformed into scores. It also gives in-depth details so developpers can fix the detected issues.
 
-**There are so many things left to do, your help would be greatly appreciated! Please report bugs, ask for evolutions and come code with me.**
+By the way, it's free because I am a geek, not businessmen. In return, you can add a ★ on GitHub, it will boost my motivation to add more awesome features!!!
+

-## Help needed
+## Install your own private instance
 
-I'm currently looking for help in correcting the english wordings in the tool, as it is not my native language.
+If your project is not accessible from outside or if you want to test your localhost, you might want to run your own instance of Yellow Lab Tools.
 
+The classical way is to clone the YLT server's GitHub repository and run it on Linux or MacOS. The documentation is [here](https://github.com/YellowLabTools/YellowLabTools/wiki/Install-your-private-server).
 
-## Install your own instance
-
-If your project is not accessible from outside, or if you want to fork and improve the tool, you can build your own instance. The documentation is [here](https://github.com/gmetais/YellowLabTools/wiki/Install-your-own-instance).
-
-
-## License
-Please read the [license](LICENSE).
-
-Icons are the property of [IcoMoon.io](https://icomoon.io/)
+The new recommended solution is to run Yellow Lab Tools inside a Docker virtual machine. My friend Ousama Ben Younes maintains [this ready-to-use Docker image based on Alpine](https://github.com/ousamabenyounes/docker-yellowlabtools)).
