Directions: To here - From here

I try to use Google Maps Mapping API to create customizable
Google Maps to embed on my website

I am looking at the API documentation
(http://www.google.com/apis/maps/documentation/ ) posted in the web
page for Google Maps API - Sign Up (
http://www.google.com/apis/maps/signup.html )

When we search for an address in http://maps.google.com/, we get map
with marker to this address. When we click on the marker we get a
pop-up window similar to the following.

Address:
1476 Millbrook Dr
Ann Arbor, MI 48108
Set as start location
Directions: To here - From here

I need an Example code to have this feature with "Directions: To here
- From here" links in my website.

Please help
