Implement Assetic library

Hi everyone,
i just used this library https://github.com/Takeno/CI_Assetic so that i can use it for my project.
Everything worked fine, but i want to minify the css and js files, and i don't know how to implement this feature. So is anyone did it?

I know i can do it manually and also there is some libraries that can handle it, but i want to have the possibility to edit the css and js files without thinking about minifying or grouping files.
Also Assetic library offer caching files so i want take advantage of all that.
