 ### A simple inline application
 
-    require 'sham_rack'
+```ruby
+require 'sham_rack'
 
-    ShamRack.at("www.greetings.com") do |env|
-      ["200 OK", { "Content-type" => "text/plain" }, ["Hello, world!"]]
-    end
+ShamRack.at("www.greetings.com") do |env|
+  ["200 OK", { "Content-type" => "text/plain" }, ["Hello, world!"]]
+end
 
-    require 'open-uri'
-    open("http://www.greetings.com/").read            #=> "Hello, world!"
+require 'open-uri'
+open("http://www.greetings.com/").read            #=> "Hello, world!"
+```
 
 ### Sinatra integration
 
-    ShamRack.at("sinatra.xyz").sinatra do
-      get "/hello/:subject" do
-        "Hello, #{params[:subject]}"
-      end
-    end
-
-    open("http://sinatra.xyz/hello/stranger").read  #=> "Hello, stranger"
+```ruby
+ShamRack.at("sinatra.xyz").sinatra do
+  get "/hello/:subject" do
+    "Hello, #{params[:subject]}"
+  end
+end
 
+open("http://sinatra.xyz/hello/stranger").read  #=> "Hello, stranger"
+```
 ### Rackup support
 
-    ShamRack.at("rackup.xyz").rackup do
-      use Some::Middleware
-      use Some::Other::Middleware
-      run MyApp.new
-    end
+```ruby
+ShamRack.at("rackup.xyz").rackup do
+  use Some::Middleware
+  use Some::Other::Middleware
+  run MyApp.new
+end
+```
 
 ### Any old Rack app
 
-    ShamRack.at("google.com").mount(my_google_stub)
+```ruby
+ShamRack.at("google.com").mount(my_google_stub)
+```
 
 ### General-purpose stubbing
 
-    @stub_app = ShamRack.at("stubbed.com").stub
-    @stub_app.register_resource("/greeting", "Hello, world!", "text/plain")
-
-    open("http://stubbed.com/greeting").read       #=> "Hello, world!"
-    @stub_app.last_request.path                    #=> "/greeting"
+```ruby
+@stub_app = ShamRack.at("stubbed.com").stub
+@stub_app.register_resource("/greeting", "Hello, world!", "text/plain")
 
+open("http://stubbed.com/greeting").read       #=> "Hello, world!"
+@stub_app.last_request.path                    #=> "/greeting"
+```
 
 ### On a specific port
 
-    ShamRack.at("example.com", 8080) do |env|
-      ["200 OK", { "Content-type" => "text/plain" }, ["Hello, world!"]]
-    end
+```ruby
+ShamRack.at("example.com", 8080) do |env|
+  ["200 OK", { "Content-type" => "text/plain" }, ["Hello, world!"]]
+end
+```
 
 Or, just use Sinatra, as described above ... it's almost as succinct, and heaps more powerful.
 
 ### Avoiding (accidental) real network connections
 
-    ShamRack.prevent_network_connections
+```ruby
+ShamRack.prevent_network_connections
+```
 
 ### When you're done testing
 
-    ShamRack.reset
+```ruby
+ShamRack.reset
 
-    open("http://stubbed.com/greeting").read       #=> OpenURI::HTTPError
+open("http://stubbed.com/greeting").read       #=> OpenURI::HTTPError
+```
 
 Supported HTTP client libraries

 ShamRack supports requests made using Net::HTTP, or any of the numerous APIs built on top of it:
 
-    uri = URI.parse("http://www.greetings.com/")
-    Net::HTTP.get_response(uri).body                      #=> "Hello, world!"

 ### Patron (experimental)
 
 We've recently added support for [Patron][patron]:
 
-    require 'sham_rack/patron'
+```ruby
+require 'sham_rack/patron'
 
-    patron = Patron::Session.new
-    patron.get("http://www.greetings.com/").body          #=> "Hello, world!"
+patron = Patron::Session.new
+patron.get("http://www.greetings.com/").body          #=> "Hello, world!"
+```
