 # wrapping_coords2d
 Rust crate to translate 2D coordinates into a 1D index with wrapping
 
-Use WrappingCoords2d to store data from a 2D grid into a 1D container such as `std::vec::Vec`. Index operations wrap around in both dimensions. This is not a container; it is just a tool to manipulate indices. For a 2D container, see [`array2d`](https://docs.rs/array2d/latest/array2d/). For coordinate translation without wrapping, see [`ameda`](https://docs.rs/ameda/latest/ameda).
+Use WrappingCoords2d to store data from a 2D grid into a 1D container such as `std::vec::Vec`. Both x and y coordinates wrap around through the limits of the grid. WrappingCoords2d is not a container; it is just a tool to manipulate indices. For a 2D container, see [`array2d`](https://docs.rs/array2d/latest/array2d/). For coordinate translation without wrapping, see [`ameda`](https://docs.rs/ameda/latest/ameda).
 
-WrappingCoords2d is useful to design cellular automata and agent-based models. Just like my [ABM project](https://github.com/facorread/rust-agent-based-models), WrappingCoords2d enables you to use the [Entity-Component-System (ECS)](https://en.wikipedia.org/wiki/Entity_component_system) software architecture.
