 # Console
 
 Simple console container, useful as a dev pod.
+
+To deploy in K8s, add the following manifest:
+
+```yaml
+apiVersion: apps/v1
+kind: Pod
+metadata:
+  name: console
+spec:
+  containers:
+    - name: console
+      image: ghcr.io/bsm/console/console:latest
+      imagePullPolicy: Always
+```
+
+To execute custom commands at boot time you can include custom init scripts into a
+`ConfigMap`. For example:
+
+```yaml
+---
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: special-config
+  namespace: default
+data:
+  10-nproc.sh: |
+    #!/bin/bash
+
+    nproc > /tmp/NPROC
+---
+apiVersion: apps/v1
+kind: Pod
+metadata:
+  name: console
+  namespace: console
+spec:
+  containers:
+    - name: console
+      image: ghcr.io/bsm/console/console:latest
+      imagePullPolicy: Always
+      volumeMounts:
+        - mountPath: "/etc/console/init/boot.d"
+          name: bootd
+  volumes:
+    - name: bootd
+      configMap:
+        name: console-boot
+```
