+# Ultra32
 A vector package using the fast float32array
+
+
+# Get started:
+
+To get started, install ultra32:
+```
+npm install ultra32 --save
+```
+
+A ultra32 vector is just a Float32Array.
+
+```
+const vec = new Float32Array([0,0]);
+```
+
+You can perform multiple operations:
+```
+add(vec,new Float32Array([1,2]));
+mul(vec,3);
+mirror(vec);
+
+console.log(vec); //Float32Array [ -3, -6 ]
+```
