For this assignment, I downloaded Monosnap, which was free in the App Store. I had an enjoyable experience using the app. Typically I press command+shift+4 for taking screenshots, but Monosnap takes it to another level. After taking the screenshot, it automatically turns it into editing mode. I utilized features such as cropping and adding text and arrows. The only downside is the text color and font are fixed, at least from what I could tell.
Once I made all of my screenshots, I put them onto a PowerPoint project with three slides. I used text boxes to indicate the steps. Finally, I did a save as PowerPoint to PDF document and uploaded it to my blog using my PDF embedder plugin.
