+# Admin
+
+## Connect to your cluster
+
+Ensure you are connected to your cluster because Warnet will use your current configuration to generate configurations for your users.
+
+```shell
+$ warnet status
+```
+
+Observe that the output of the command matches your cluster.
+
+**TODO** Add the *current-config* to the *status* report.
+
+## Create an *admin* directory
+
+```shell
+$ mkdir admin
+$ cd admin
+$ warnet admin init
+```
+
+Observe that there are now two folders within the *admin* directory: *namespaces* and *networks*
+
+## The *namespaces* directory
+This directory contains a Helm chart named *two_namespaces_two_users*.
+
+Modify this chart based on the number of teams and users you have.
+
+Deploy the *two_namespaces_two_users* chart.
+
+```shell
+$ cd namespaces
+$ warnet deploy two_namespaces_two_users
+```
+
+**TODO**: `warnet deploy namespaces/two_namespaces_two_users` fails with an error about directory handling
+
+Observe that this creates service accounts and namespaces in the cluster:
+
+```shell
+$ kubectl get ns
+$ kubectl get sa -A
+```
+
+**TODO**: `warnet admin namespaces list` does not show the teams as yet.
+
+**TODO**: Lift `kubectl get sa -A` into Warnet.
+
+### Creating Warnet invites
+A Warnet invite is a Kubernetes config file.
+
+Create invites for each of your users.
+
+```shell
+$ warnet admin create-kubeconfigs wargames
+```
+
+Take note of the "wargames" prefix we used. That aligns with the "wargames" prefix of the namespaces we created for our users.
+
+Observe the *kubeconfigs* directory. It holds invites for each user.
+
+### Using Warnet invites
+Users can connect to your wargame using their invite.
+
+```shell
+$ warnet auth alice-wargames-red-team-kubeconfig
+```
+
+### Set up a network for your users
+Before letting the users into your cluster, make sure to create a network of tanks for them to view.
+
+
+```shell
+$ warnet admin deploy networks/mynet --namepace wargames-red-team
+```
+
+**TODO**: What's the logging approach here?
+
+Observe that the *wargames-red-team* namespace now has tanks in it.
