@prune998 I have now setup a gh-pages branch and defined the output folder as charts. Can you update this PR to use charts instead of docs, then we can try it out.

looking into it, thanks @mikkeloscar

the docs folder is the one on master, where the chart files are. So I guess we should be good to go.
Sadly, I can't test it until we merge this PR...
