+This lab is broken down into a set of 10 unique modules that explore a variety of tools. There is no specific ordering or pre-requisite to move between each module, but we do recommend you review `Module 1` and `Module 2`.
 
 Once you have reviewed `Module 1` and `Module 2`, feel free to continue to `Module 3` or pick one that interests you the most.
 
-. Module 1 introduces all of the tools we will be using
-. Module 2 does a deeper dive on the functionality in the `omc` tool
-. Module 3 uses `omc` to explore an issue with a vSphere IPI cluster
-. Module 4 uses `kubectl-dev_tool` to explore a cluster with an overloaded OpenShift API
-. Module 5 uses `ocp_insights.sh` to proactively look for performance issues with OpenShift Insights data
-. Module 6 uses `etcd-ocp-diag.sh` to review etcd logs for performance related issues
-. Module 7 uses `omc` to review Cluster Upgrades
-. Module 8 uses `omc` to review install OLM Operators
-. Module 9 uses `omc` and _manual checks_ on the cluster must-gather in order to explore an OCP networking issue
