Generate some RSS/Atom feeds for your Jekyll blog.

Add the following to your Gemfile:

group :jekyll_plugins do
  gem 'jekyll-rss'
end

Execute the rss_templates Jekyll subcommand to generate the necessary templates onto your source directory:

jekyll rss_templates --blog --category

This will create an _rss directory on your source directory with two files -- blog.xml and category.xml, which is read by the generator to generate the all-encompassing feed and the categorized feeds respectively.

You can omit either --blog or --category depending on your needs.

Next step is to enable the plugin by adding this to your _config.yml:

rss: true

or

rss:
   paginate: 5 #Number of posts per page.

The permalink for the feeds can be configured from within the front-matter of the template files.

_rss/blog.xml:

permalink: /rss/feed.xml
paginated_permalink: /rss/:num/feed.xml

/rss/feed.xml, /rss/1/feed.xml, /rss/2/feed.xml, etc.

rss/category.xml

permalink: /rss/:category.xml
paginated_permalink: /rss/:num/:category.xml

/rss/foobar.xml, /rss/1/foobar.xml, /rss/2/foobar.xml, etc.

Note that the permalink must end with .xml, so that the proper content type is detected even when using the least capable of web-servers i.e. a public hosted directory like an Amazon S3 bucket.
