 **All Params are only accessible using all lowercase characters.**

+### Param method

+In Hugo you can declare params both for the site and the individual page.  A common use case is to have a general value for the site and a more specificy value for some of the pages (i.e. an image). 

+

+With the `Param` method the most specific value will be selected for you, and it is safe to use it in any template (it's defined on both Page and Node):

+

+```

+$.Param("image")

+```

+

 ## Node Variables

 In Hugo, a node is any page not rendered directly by a content file. This

 includes taxonomies, lists and the homepage.
