Adding comments via Disqus to your Jekyll blog is something you probably want to do if you want a bit of life and interaction. Good news: it couldn't be easier.
There are installation instructions on the Disqus documentation, and on various places around the web, but I thought I would recap the lot for y'all.
"Great discussions are happening here"... so Disqus says. Unless nothing much will in fact happen, and you're fine with this.
Then generate a custom script for Jekyll, you'll need to use the Universal Code option here.
Copy your script and paste it into a disqus.html template in /_includes. Make sure you surround the script between the if page.comments and endif liquid code lines.
Then edit your _config.yml file to add the "comments: true" bit...
defaults: - scope: path: "" # an empty string here means all files in the project type: "posts" # previously `post` in Jekyll 2.2. values: author: flo preynat layout: "post" comments: true
Finally, go to your /layouts/post.html template and add **include disqus.html disqusidentifier=page.disqus_identifier** (between liquid handles) below the end of your blog post.
