 ### Browser Shimming Leveldown
-As `leveldown` does not work in the browser, `LevelStore` takes advantage of the browser property in package.json to shim `level-js` in its place. Most modern bundlers such as webpack, will see the shim and replace it for use in the browser. If you are using a bundler that does not support pkg.browser, you will need to handle the shimming yourself, as was the case with versions of `LevelStore` 0.7.0 and earlier.
 
+`LevelStore` uses the `level` module to automatically use `level.js` if a modern bundler is used which can detect bundle targets based on the `pkg.browser` property in your `package.json`.
