 ## Installation
 
 ```npm i -S simplex-noise```
 
 ## Usage
 
+```javascript
+// when using es modules
+import SimplexNoise from 'simplex-noise';
+// when using commonjs
+const {SimplexNoise} = require('simplex-noise');
+```
+
 By default simplex-noise.js will use Math.random() to seed the noise.

 ## Benchmarks
 
-- [Comparison between 2D and 3D noise](http://jsperf.com/simplex-noise/4)
-- [Comparison with simplex implementation in three.js](http://jsperf.com/simplex-noise-comparison/3)
+simplex-noise.js is reasonably quick.
+According to `perf/benchmark.js` I can perform about 50 million `noise2D()` calls/second on a single thread on my desktop (Ryzen 5950X).
+So ~20 nanoseconds per call.
 
-For development you can open `perf/index.html` and watch the console or run `node perf/benchmark.js` in a shell.
-There is also a rake task for comparing your current changes can also run `make compare`.
-The command works using git stash.

 ## Changelog
 
-### main
+### 3.0.0
+- Changed module structure. When using bundlers that import the es module even using require() the import might need to be updated.
 - Dependency update
 - Setting sideEffects: false in package.json
 - Added snapshot tests
