After adding mdg:chromatic as noted at https://github.com/meteor/chromatic, I’m unable to see anything at /styleguide as noted in the documentation below at the github link…
In github, under ‘usage’ section for mdg:chromatic, it says: “Chromatic is available at /styleguide in your app in development mode”.
What version of Meteor are you using? There’s a known issue around 1.3 that we’re working to resolve. Report issues here please: https://github.com/meteor/chromatic/issues
