This is a multi-step process but one that is relatively easy once you get the hang of it.
1 - Download the app to your smartphone
2 - insert the wifi adapter on your camera
3 - with the camera turned on - from your smartphone select the camera wifi spot
4 - from the camera select the pictures you want to transfer
5 - from the smartphone, load the app and select 'download' pictures.
The list above is from memory but those are the basic steps.
Enjoy.
