-# gitops-must-gather
-A client tool for gathering GitOps Operator information in a OpenShift cluster.
+# GitOps Operator Must-Gather
+=================
+
+`GitOps must-gather` is a tool to gather information about the gitop-operator. It is built on top of [OpenShift must-gather](https://github.com/openshift/must-gather).
+
+### Usage
+```sh
+oc adm must-gather --image=quay.io/redhat-developer/gitops-must-gather:latest
+```
+
+The command above will create a local directory with a dump of the OpenShift GitOps state. Note that this command will only get data related to the GitOps Operator in your OpenShift cluster.
+
+You will get a dump of:
+- Information for the subscription of the gitops-operator
+- The GitOps Operator namespace (and its children objects)
+- All namespaces where ArgoCD objects exist in, plus all objects in those namespaces, such as ArgoCD, Applications, ApplicationSets, and AppProjects, and configmaps
+  - No secrets will be collected
+- A list of list of the namespaces that are managed by gitops-operator identified namespaces and resources from those namespaces. 
+- All GitOps CRD's objects and definitions
+- Operator logs
+- Logs of Argo CD
+- Warning and error-level Events
+
+In order to get data about other parts of the cluster (not specific to gitops-operator) you should run just `oc adm must-gather` (without passing a custom image). Run `oc adm must-gather -h` to see more options.
+
+An example of the GitOps must-gather output would be something like the following, where there are two argocd instances in namespaces `openshift-gitops` and `foo` and an additional namespace called `foo-managed` which is managed by namespace `foo`:
