-# Helm Chart for deployment of Ladder
-This folder contains a basic helm chart deployment for the ladder app.  
-
-# Deployment pre-reqs
-## Values
-Edit the values to your own preferences, with the only minimum requirement being `ingress.HOST` (line 19) being updated to your intended domain name.  
-
-Other variables in `values.yaml` can be updated as to your preferences, with details on each variable being listed in the main [README.md](/README.md) in the root of this repo.  
-
-## Defaults in K8s
-No ingress default has been specified. 
-You can set this manually by adding an annotation to the ingress.yaml - if needed.  
-For example, to use Traefik - 
-```yaml
-metadata:
-  name: ladder-ingress
-  annotations:
-    kubernetes.io/ingress.class: traefik
-```
-
-## Helm Install
-`helm install <name> <location> -n <namespace-name> --create-namespace`  
-`helm install ladder .\ladder\ -n ladder --create-namespace`  
-
-## Helm Upgrade
-`helm upgrade <name> <location> -n <namespace-name>`  
-`helm upgrade ladder .\ladder\ -n ladder`
