title: Helm merge and dict directives?
body: <p>I one of Helm chart examples I come across the following lines:</p>
  
  <pre><code>{{- define "common.deployment" -}}
  {{- $common := dict "Values" .Values.common -}} 
  {{- $noCommon := omit .Values "common" -}} 
  {{- $overrides := dict "Values" $noCommon -}} 
  {{- $noValues := omit . "Values" -}} 
  {{- with merge $noValues $overrides $common -}}
  </code></pre>
  
  <p>But I can't find in helm docs information about omit, merge and dict directives.</p>
