Diagramming software - You may use Microsoft Visioor a free Open Source option called Lucidchart, available at https://www.lucidchart.com/. A free single user option is available if you sign up on the website. Be sure to read the terms of service for full details. SmartDraw also has a free download available at https://www.smartdraw.com/resources/tutorials/entity-relationship-diagrams/
Screen snapshots can be made by hitting the PrtScrn button on the keyboard and then pasting the captured image into Word. You can use Alt-PrtScrn to capture a single window of interest vs. the entire display on the monitor.
