Hi, I downloaded Markdownify from http://milianw.de/projects/markdownify/ and extracted it to my application/libraries/ directory.

I did a:

Code:

$this->load->library('markdownify');
echo $this->markdownify->parseString('<b>Test</b>');

But the output is the same html (<b>Test</b>). It didn't work. Did I do something wrong?
