docpad - My markdown files are showing html tags in the browser -

i using docpad static site generator. have run docpad install marked on command line.

my markdown file about.html.md contains this:
long walks on beach. _plus rock @ docpad!_

when @ site in browser, see actual tags:

<p>i long walks on beach. <em>plus rock @ docpad!</em></p> 

obviously want see is:

i long walks on beach. plus rock @ docpad!

i using nunjucks tempting engine through consolidate plugin if makes difference...

according documentation, autoescaping turned on default in nunjucks templating engine security precaution (typical of templating engines). if passing html template , want html rendered without escaping, need tell template "safe":

{{ foo | safe }} 

alternatively, globally turn escaping off, not recommended. if want anyway, docs state can "pass autoescape option false environment object":

var env = nunjucks.configure('/path/to/templates', { autoescape: false }); 

i'm not familiar consolidate plugin docpad, presumably passing { autoescape: false } option consolidate accomplish same thing.
