 # Tips
 
 - Use [helm diff](https://github.com/databus23/helm-diff) to preview changes
 - We don't version this chart at this time
 - Set image.tag to the GlitchTip version you wish to install
+- Set redis.auth.password to avoid redis being entirely remade on each release
+- If updating the chart, carefully review values for any new defaults
