Do I need to download an SDK separately from the software for MacAir2? Are there examples of infographics others created?

I must have missed the calls to action on the homepage (i.e., Mac or PC then version ,etc. an “Example Projects” tab, etc.) so I just downloaded. I hope it’s useful but this feels like old Microsoft - no intro or anything. Unless it’s all inside.

I thought you might want feedback on initial experience. Ironically trying to use this to create infographics about on-boarding, etc. Thank you for your help.
