== Steps ==
#Log into your Google Maps account.
#Click on the MY MAPS link near the top left.
#Click on the CREATE NEW MAP link near the top left.
#Now you can see the new ‘Untitled’ map you’ve started as well as the map editing tools you’ll use to create your map.
#Click on Blue peg in your tools area, then click the physical map to place your marker on the map. You’re up and running!
#Explore the editing tools and get comfortable with the different ways of developing a map. You can use simple HTML to format your information windows, add images, create links, color type, and, of course, make your own map marker.
#One last thing, when adding a Google map to a web page or blog, you will need a key from Google Maps API (http://code.google.com/apis/maps/index.html). The key is for a particular url, just follow the instructions at the url above for plugging in your map.
#Good luck!
