👋 @larivierec, thanks for taking the time to submit this PR. 🙏🏽

We have noticed that the chart documentation has not been completely updated for this PR.
Could you please make sure that the following items have been updated:

• version in Chart.yaml has been updated per semver
• README_CHANGELOG.md.gotmpl contains a summary of the updates for this new version
• Documentation strings have been added to the keys in values.yaml.

Afterwards you can run ./hack/gen-helm-docs.sh stable <chart> again to update the chart's README.md file.

Please also bump the chart version by feature not patch. Thanks!

[larivierec]

Will do, realized I also forgot to do what the bot mentioned.

I'll do them both tomorrow at the same time

[larivierec]

should be good. let me know if there's anything else i can do.
cheers

Please re-read the bot reply above. They way you currently made changes to the README.md will be overwritten because you didn't update the template instead. Make sure you re-run helm-docs afterwards too

[larivierec]

Yes, I believe it is ok now. I added a new commit the README.md is resulting from the following command ./hack/gen-helm-docs.sh stable mealie which I ran from the root however, it was my fault for not having to add it to the template for the changelog, nice spot.
