 Require from a directory relative to node_modules, flattening your require paths. Using requireFrom you won't have to manage complex relative paths between each component of your node app.
 
+Alternatively check out [wavy](https://www.npmjs.com/package/wavy) or [link-local](https://www.npmjs.com/package/linklocal) if symlinks might be a better solution for your project.

 ## Code Example
 
 Simple usage anywhere in your node app:
 ````js
-    var lib = require('requirefrom')('lib');
-    var myModule = lib('myModule');
+    let lib = require('requirefrom')('lib');
+    let myModule = lib('myModule');

 Any file in this project could then include these files with the following code:

 Without requireFrom, each file would need to maintain paths relative each other file, for example:
 ````js
