@adrianmoisey, just want to confirm, that Can I run the VPA in an HA configuration? is under the I get recommendations for my single pod replicaSet but they are not applied content if yes then it should be
#### Can I run the VPA in an HA configuration? instead of ## Can I run the VPA in an HA configuration?

If not(which I think) then it should be ### Can I run the VPA in an HA configuration? and you have to mention this under the Contents
