There is "5.3. Deploying CodeReady Workspaces with support for Git repositories with self-signed certificates" which needs to be aligned with CodeReady Workspaces

1. Redundant point "If CodeReady Workspaces is deployed using a Helm Chart"
2. Next command should be corrected: "oc patch checluster eclipse-che -n che" > "oc patch checluster codeready-workspaces -n workspaces"

Feel free to ask Maksym Musienko about more details: he is testing this feature.
