 NumIdr is a linear algebra and data manipulation library for Idris 2. It features
 an efficient, type-safe array data structure, as well as utilities for working with
-vector spaces and matrices. It borrows concepts heavily from Python's [NumPy](https://numpy.org/),
-as well as Rust's [nalgebra](https://www.nalgebra.org/).

-## Planned Features
+## Inspiration
 
-- An IO-based mutable array type, useful for writing more efficient code.
+NumIdr is inspired by many different data science and linear algebra libraries,
+including Python's [NumPy](https://numpy.org/), Rust's [nalgebra](https://www.nalgebra.org/),
+and Haskell's [massiv](https://hackage.haskell.org/package/massiv). It aims to
+combine the most useful features of each library.
