 ## Helm Charts for Minds
 
-WIP
+### Pipes are your friend
+
+The settings.php generated by the interpolation of settings.yaml is very fragile.
+
+Fortunately, helm provides pipes for handling some formatting issues.
+
+1. Bools and ints should *not* be quoted
+2. You can set a reasonable default with ```{{ .Values.key | default "value" }}}```
+3. You can ensure your values are quoted with ```{{ .Values.key | quote }}```
+4. To properly escape an empty string ```{{ .Values.key | default "" | quote }}```
+
+### Testing
+
+No more shipping broken templates!
+
+```
+helm install --dry-run --debug ./minds
+```
+
+This will output all the files generated by helm and allows you to spot check settings.php to make sure your changes look right.
