Feature Summary

Would a PR be accepted to rewrite the basic install guide? I think as it stands it is hard to follow and has to much information. I think it would be better if it used helm and had less information. Right now it is really unclear how everything all comes together and it isn't really skimable. Ideally it should be much shorter and be much more to the point. I think is should be purely a getting started guide and any unneeded info should be moved to a separate page.

For my install I used helm and then set the service_type to loadbalancer. From there I created a ingress to expose port 80.

I'd love to use AWX but this is the hardest application to install I've encountered on the internet thus far.
