Hi Breanna. Different people learn different ways and of course we try to accommodate as many of these as possible. I would recommend starting here: http://coronalabs.com/resources/tutorials/getting-started-with-corona/
There are text tutorials, video tutorials, pointers to 3rd party tutorials, which should help get you started. On your Mac in /Applications/CoronaSDK/SampleCode are a bunch of sample apps that you can look into to see how things are done.
Right now, Corona SDK requires quite a bit of Lua to get started. You will need a text editor (we recommend Sublime Text, but it’s not free) that you’re comfortable with. Generally you make a folder, copy open of the sample apps to your code (so you get all of the frame work: config.lua, build.settings, starter Icons, launcher images, and a main.lua.) and go to town.
Welcome to Corona!
