Tell me how the library works nikic/FastRoute
Downloaded this library and can not on this basis to develop a simple routing.
for example: clicking on the link site.com/ - otkryvaetsya template in the root folder /templates/theme1/index.tpl by clicking on the link site.com/admin - open the administration panel by clicking on the link site.com/articles/1/ -- opening page of the article first page etc.
But most of what you need to learn and understand what is written in this library.
Please help. If something is not clear, please do not judge strictly, as I'm a beginner developer.
