Type your address or post code in the search bar - click 'search maps'
This should zoom you to where you 'grow' or live.
Under where it says 'google maps uk' click on the tab that says 'My maps' (so you put your pin in the main map where evryone else is).
On the left hand menu (to the right of HWs piccy) click 'edit'
On the map (top left) click on the blue pin (looks like a balloon) and then drag it to where you want it to be, click again to 'set' it.
A box appears - type your details in the Title (and description if you like) then click Okay.
Back on the left hand menu (near HW's piccy) click Save, then click Done.

That should be you added to the Grapes Map?
