From the Page manager, click on the "About" page on the lefthand side.
From there, select Edit next to the Address section.
Enter your location's address. If the address is valid, a map will appear. If a map does not appear, you may need to reformat your address (i.e. "street' instead of st.). Once the map shows up, you can check the box below that says "Show map and check-ins on the Page". Save Changes.
Once you return to your Home page, you should see the map showing. Once you begin receiving check-is, you will see an added metric showing "X were here" to show your check-ins.
