Word is actually really great for this stuff. You get a portable file and can add notes to the screenshots. There is even a screenshot button built into Word!

Word is actually really great for this stuff. You get a portable file and can add notes to the screenshots. There is even a screenshot button built into Word! For recordings, if you use Windows you can bring up the game bar with Win+G. It has a very easy to use screen capture tool meant for gaming, but perfectly fit for small software demos. It even captures sound which is sometimes useful.
