How to use third party library

From the doc first you need to download Composer which will install it.

Once Composer is installed you need to run it from a terminal in the project root.

composer require mobiledetect/mobiledetectlib

Once installed just follow the rest of the instructions.

Tnx, but I forgot to metnion that I will not install it with composer, but manualy include in my project. I need to put mobileDetect.php somwhere and somehow include it in app....
