# Package by features

The directory structure is the very first thing encountered by a programmer when browsing source code. Everything flows from it. Everything depends on it. It is clearly one of the most important aspects of your source code.


### Gains and Benefits

* Higher modularity;
* Easier code navigation;
* Higher level of abstraction;
* Separates both features and layers;
* More readable and maintainable structure;
