hmm, I'm not sure about using HTML tags, they make README better but the values.yaml is a bit messy.

I would also like to keep markdown tables instead of html ones, but multiline content breaks markdown tables and markdown is not rendered inside html. I can add to hugo-docs a PR, which adds function, which allow markdown to html conversion

removed HTML tags from values and and rendered documentation by helm-docs binary from this PR
temporary added docker image that contains my fork

@Haleygo
Since there's no activity in helm-docs repo for a month, so I've built a docker image with my fork
could you please review it again?

A minor question: is there a way to support value's comment without adding the prefix # --?
I'm just concerned that I or other contributors might forget to add this for new values in the future.

[AndrewChubatiuk]

as far as i know and also you can see it in code helm-docs expects all comments to start with # -- to take them into account. Also I like this idea as this approach allows to put a whole YAML subtree in a values column if it's comment starts with #--, which is useful in a case of huge configuration object, like some CR spec, or alertmanager config, etc without a need to document each default parameter
