In case anybody is interested, I wrote up detailed instructions for setting up Discourse.org comments for an Octopress blog. The cool thing is that you can now use discourse for commenting on my blog!
The “Rails” connection is that my blog is about Rails, and it’s commenting engine is now powered by the Rails/Ember app Discourse.org running on Docker.
