Answer 1

Redcarpet

When you want to use redcarpet there seems to be no convenient solution right now. Although Redcarpet 3 supports footnotes with the syntax you've used, it is not included into Jekyll, because Redcarpet 3 removes Ruby 1.8 compatibility (source).

Solution 1: Use forked Redcarpet 2

See this solution by Jerod Santo:

Add a file called Gemfile to the root of your Jekyll folder with this content:

source "https://rubygems.org"

gem "jekyll"
gem "redcarpet", github: "triplecanopy/redcarpet"

or alternatively djui/redcarpet

Theny adjust your _config.yml to

markdown: redcarpet
redcarpet:
  extensions: [footnotes]

Solution 2: Fork Jekyll and include Redcarpet 3

I don't know what's the easiest way to do this. Comments are welcome.
