 This pipeline will update the `my-deployment` deployment with the image tagged `DRONE_COMMIT_SHA:0:8`
 
+```yaml
     pipeline:
         deploy:
             image: quay.io/honestbee/drone-kubernetes
             deployment: my-deployment
             repo: myorg/myrepo

 Deploying containers across several deployments, eg in a scheduler-worker setup. Make sure your container `name` in your manifest is the same for each pod.
     
+```yaml
     pipeline:
         deploy:
             image: quay.io/honestbee/drone-kubernetes
             deployment: [server-deploy, worker-deploy]
             repo: myorg/myrepo
             container: my-container
-            tag: ${DRONE_COMMIT_SHA:0:8}
+            tag:                 
+                - mytag
+                - latest
+```
 
 Deploying multiple containers within the same deployment.
 
+```yaml
     pipeline:
         deploy:
             image: quay.io/honestbee/drone-kubernetes
             deployment: my-deployment
             repo: myorg/myrepo
             container: [container1, container2]
-            tag: ${DRONE_COMMIT_SHA:0:8}
+            tag:                 
+                - mytag
+                - latest
+```
 
 **NOTE**: Combining multi container deployments across multiple deployments is not recommended
