Some easy fixes for someone wanting to get their feet wet

An individual opened a handful of issues flagging Failure techniques missing references to other techniques.

Each of these should be a simple change, and I’d encourage anyone new to the group or wanting to get more involved to pick one (or more) up, read it over to see if you agree, and generate a PR. If you have any questions or issues, feel free to reach out to me or Bruce.

Have a good weekend!
