-### Getting Info About The Parsed Files
-php.less can tell you which .less files were imported and parsed.
+### Caching CSS
+Use the Less_Cache class to save and reuse the results of compiled less files. 
+This method we check the modified time of each less file (including imported files) and regenerate when changes are found.
+Note: When changes are found, this method will return a different file name for the new cached content.
 
 ```php
 <?php
-$parser = new \Less\Parser();
-$parser->parseFile( '/var/www/mysite/bootstrap.less', '/mysite/' );
-$css = $parser->getCss();
-$imported_files = $parser->allParsedFiles();
+$to_cache = array( '/var/www/mysite/bootstrap.less' => '/mysite/' );
+Less_Cache::$cache_dir = '/var/www/writable_folder';
+$css_file_name = Less_Cache::Get( $to_cache );
+$compiled = file_get_contents( '/var/www/writable_folder/'.$css_file_name );

-### Caching to Improve Performance
-php.less will save serialized parser data for each .less file if a writable folder is passed to the SetCacheDir() method.
-Note: This feature only caches intermediate parsing results to improve the performance of repeated css generation.
-Your application should cache any css generated by php.less.
