Routing in Ruby on Rack?

Question

ruby

Good day to all. I am writing a small web application. I haven't touched Sinatra and Rails yet.
In config.ru:

require 'rubygems'
require 'rack'

map '/index' do
  require './index'
  run Index.new
end
map '/about' do
  require './about'
  run About.new
end

So far so good, but I would like to write something like:

map '/articles/:id' do
  #тут выбираем статью по идентификатору
end

So far, all attempts and searches have been unsuccessful. Thank you all in advance.
