 # filesize.js
+
 filesize.js provides a simple way to get a human readable file size string from a number (float or integer) or string.  An optional second parameter is the decimal place to round to (default is 2), or _true_ which triggers Unix style output. The maximum supported size is a terabyte. When hard drives get bigger, I'll add support for petabytes.
 
 ## Examples
+
 ``` js
 filesize(1500);                   // "1.46KB"
 filesize("1500000000");           // "1.40GB"
@@ -11,11 +13,15 @@ filesize(1212312421412412, true); // "1102.6T" - shorthand output, similar to *n
 ```
 
 ## How can I load filesize.js?
+
 filesize.js supports AMD loaders (require.js, curl.js, etc.), node.js & npm (npm install filesize), or using a script tag.
