@wajihaparvez a few changes that needs to be made:

1. On page under 'Metrics storage location:' need to indicate that these are AWS regions.
2. In the section Disconnect a cluster I think it would be clear to start the process from step 2 and then go to step 1 and 3, 4....
3. Also the disconnect can also be done from Cloud home and not only from the connected clusters page. so we can mentioned this as well.

4. I cannot find this update implemented in the pages you linked.

Just to be 100% sure, is this really supposed to be "the / endpoint? I thought it might have some path, but I guess it's the very top level of the API.

Thanks @kilfoyle! @arnonst can you please confirm?

[arnonst]

@wajihaparvez @kilfoyle the API call 'GET /' is a valid one

LGTM! 🏎️
Just one small question about the / endpoint.

@arnonst Thanks for reviewing! I've made all the changes you pointed out.
About point 4, as we were discussing in the issue comments, I clarified the wording on the Connect your self-managed cluster to AutoOps page (line 110)
