Use Explainer Screenshots if you ever explain "computer stuff" to other people. Instead of writing long winded emails filled with screenshots, or spending time on the phone, use the Explainer app. Explainer app is for those times when a single screenshot is not enough, but a screen recording too much of a hassle. You can capture multiple screenshots into a single image. Add a caption or large cursor, done.
