Once installed as a module for the webserver, WebDNA looks for two things:

- the .dna extension for your WebDNA pages
- The html comment <!--HAS_WEBDNA_TAGS--> at the top of your WebDNA pages

Is this mandatory? No, you can override these requirements in the settings. But for now, let's use .dna as the extension and put <!--HAS_WEBDNA_TAGS--> at the top of the pages.

A basic WebDNA tag is [date]. Note the syntax: the WebDNA language is built to understand square brackets.

Create a page named "test.dna" in your root webserver (on a Mac, this is /Library/WebServer/Documents/) and enter the following code:


<!--HAS_WEBDNA_TAGS--> [date]

That's it! Using your browser, call your local server with this address:

http://127.0.0.1/test.dna

You should see today's date.

Simple, isn't it? What if you want another date format? Try this: [date %A, %B %d, %Y]. This will show the day, month, date and year in the format of Thursday, August 14, 2012. You will find all the date formats here
