Happy to! It's really pretty straightforward using the built-in Alexa integration. Documentation is here. Give it a shot and if you have any questions just ask.

If you really want to have some fun you can also add the ability for HE to control Alexa devices rather than the other way around. This means you can use Alexa devices for notifications, play sounds, run commands, and so on, all from HE rules. It's a community-supported app and a little complicated to set up but many of us use it.
