Hi Laura,
 I have gone through doc which was shared by Anajana.

https://access.qa.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/2.0/html-single/deploying_red_hat_hyperconverged_infrastructure_for_virtualization_in_the_data_center/

In "Template for a single node deployment: single-node.conf"
We should also have to mention LVMCache and VDO configuration but it is optional.
If user wants vdo, LVM Cache then the config needs to be in single-node.conf file.

Other than that it looks good to me.

I would recommend to have VDO section too in the template, as I see from the template, VDO section is missing.

Some more comments:

1. chapter-3 mentions to use either RHVH or RHEL. That should be made only in to RHVH. Or is there specific reason behind support on RHEL from Sean ?

2. Content in the first paragraph under chapter-5, explains as though there are 3 nodes. ( Hope the content is reused from RHHI deployment guide :) ). We need to change it as the deployment is happening only on one node.

3. First Prerequisites under chapter-5 is:
"Configure Red Hat Gluster Storage for Hosted Engine using the Cockpit UI"

This is not possible from cockpit UI. Instead, it should be 'Configured Red Hat Gluster Storage volume for Hosted Engine using the example script'

4. First step under 'Procedure' under chapter-5 also needs the change
It says "Continue from Configure Red Hat Gluster Storage for Hosted Engine using the Cockpit UI or Log in to Cockpit". Instead just say "Log in to Cockpit"

5. Step-5 in the procedure needs little change.
Here user needs to provide the 'Storage connection' value, and no gluster mount options. Screenshot needs to be changed. Also the content should explain the same.

6. Screenshot under step8 in procedure, show 3 hosts in the cluster. Rather it should show only one

Validated the content. The gdeploy config file needs little update and that is tracked with BZ 1552559.

Verifying the content for the procedure to deploy RHHI in DC
