# Welcome to Shipyard!
[Shipyard](https://github.com/leudz/shipyard) is an Entity Component System focused on usability and speed. ECS is a great way to organize logic and data.
There are two main benefits to using an ECS:
1. Elegant approach for humans
- Composition over inheritance
- Separation of concerns
- Less burdened by lifetimes
2. Optimal design for computers
- Spatial locality
- Less pointer chasing
However, programming with an ECS requires thinking about data and logic in a different way than you might be used to.
# How does it work?
Components hold data. Entities are simple ids used to refer to a group of components.
Systems do the heavy lifting: updating components, running side-effects, and integrating with other parts of the code.
