Seems like this getting started guide is very out of date with the current version of OLM. You can follow the instructions here: https://github.com/operator-framework/operator-lifecycle-manager/blob/master/Documentation/design/building-your-csv.md to create a CSV.
The docs here: https://github.com/operator-framework/operator-lifecycle-manager/blob/master/Documentation/design/operatorgroups.md explain OperatorGroups and multitenancy with OLM.
To install a CSV, you need to include the CSV plus any CRDs and a package.yaml file into a operator-registry pod. These steps are defined in the operator-registry repo of this org.
You can also find working examples of community submitted operators in the repo here: https://github.com/operator-framework/community-operators
We should update this repo with more up to date documentation and examples.

We've updated the instructions in #36 to include the step for creating the OperatorGroup.
But as @SamiSousa mentioned we're going make extensive updates to the OLM section to reflect the current workflow of installing an operator with OLM.

Closing this in favor of #37
