+# Vector 2D
+
+[![Downloads][downloads-badge]][downloads]
+[![Size][size-badge]][size]
+
+```
+npm install @decoy9697/vector
+```
+
+This library defines a `Vector` as a tuple with 2 floats: `[number, number]`
+
+It exposes the following functions for working with these vectors:
+
+| Name            | Type                         |
+| --------------- | ---------------------------- |
+| add             | `(Vector, Vector) => Vector` |
+| cross           | `(Vector, Vector) => number` |
+| degreesToVector | `(number) => Vector`         |
+| distance        | `(Vector, Vector) => number` |
+| dot             | `(Vector, Vector) => number` |
+| length          | `(Vector) => number`         |
+| multiply        | `(Vector, number) => Vector` |
+| normalise       | `(Vector) => Vector`         |
+| radiansToVector | `(number) => Vector`         |
+| subtract        | `(Vector, Vector) => Vector` |
+| vectorToRadians | `(Vector) => number`         |
