+The following table lists the configurable parameters of the netdata chart and their default values.

+{{ template "chart.valuesTableHtml" . }}


HTML because it renders better the multiline comments and values + adds some extra feats like copy, colors. Any markdown parser will render it no problem anyway.

      - name: Run chart-testing (install)
        run: ct install --target-branch ${{ github.event.repository.default_branch }}
+
+      - name: Run chart-testing (install with OpenTelemetry)


an extra for easier problem catching, in theory we can just use this one and delete the regular install. Good thing is that at the end of the ct install there is a cleanup so they are both independent.

Last thing left for now is to make docs a bit more readable, after that it should be ready for review
