+Application templates are simple ruby files containing DSL for adding plugins/gems/initializers etc. to your freshly created Rails project or an existing Rails project.

 endprologue.
 
-h3. Introduction
+h3. Usage
 
-Application templates are simple ruby files containing DSL for adding plugins/gems/initializers etc. to your freshly created Rails project or an existing Rails project.
+To apply a template, you need to provide the Rails generator with the location of the template you wish to apply, using -m option :
+
+<shell>
+$ rails blog -m ~/template.rb
+</shell>
+
+It's also possible to apply a template using a URL :
+
+<shell>
+$ rails blog -m http://gist.github.com/31208.txt
+</shell>
+
+Alternatively, you can use the rake task +rails:template+ to apply a template to an existing Rails application :
+
+<shell>
+$ rake rails:template LOCATION=~/template.rb
+</shell>
+
+h3. Template API
+
+Rails templates API is very self explanatory and easy to understand. Here's an example of a typical Rails template :
+
+<ruby>
+# template.rb
+run "rm public/index.html"
+generate(:scaffold, "person name:string")
+route "map.root :controller => 'people'"
+rake("db:migrate")
+
+git :init
+git :add => "."
+git :commit => "-a -m 'Initial commit'"
+</ruby>
+
+The following sections outlines the primary methods provided by the API :
+
+h4. gem(name, options = {})
+
+Adds a +config.gem+ entry for the supplied gem to the generated application’s +config/environment.rb+.
+
+For example, if your application depends on the gems +bj+ and +hpricot+ :
+
+<ruby>
+gem "bj"
+gem "hpricot", :version => '0.6', :source => "http://code.whytheluckystiff.net"
+</ruby>
+
+Please note that this will NOT install the gems for you. So you may want to run the +rake gems:install+ task too :
+
+<ruby>
+rake "gems:install"
+</ruby>
+
+And let Rails take care of installing the required gems if they’re not already installed.
+
+h4. plugin(name, options = {})
+
+Installs a plugin to the generated application.
+
+Plugin can be installed from Git :
+
+<ruby>
+plugin 'authentication', :git => 'git://github.com/foor/bar.git'
+</ruby>
+
+You can even install plugins as git submodules :
+
+<ruby>
+plugin 'authentication', :git => 'git://github.com/foor/bar.git', 
+                         :submodule => true
+</ruby>
+
+Please note that you need to +git :init+ before you can install a plugin as a submodule.
+
+Or use plain old SVN :
+
+<ruby>
+plugin 'wtfsvn' :svn => 'svn://crap.com/wtf/trunk'
+</ruby>
+
+h4. vendor/lib/file/initializer(filename, data = nil, &block)
+
+Adds an initializer to the generated application’s +config/initializers+ directory.
+
+Lets say you like using +Object#not_nil?+ and +Object#not_blank?+ :
+
+<ruby>
+initializer 'bloatlol.rb', <<-CODE
+class Object
+  def not_nil?
+    !nil?
+  end
+  
+  def not_blank?
+    !blank?
+  end
+end
+CODE
+</ruby>
+
+Similarly +lib()+ creates a file in the +lib/+ directory and +vendor()+ creates a file in the +vendor/+ directory.
+
+There is even +file()+, which accepts a relative path from +RAILS_ROOT+ and creates all the directories/file needed :
+
+<ruby>
+file 'app/components/foo.rb', <<-CODE
+class Foo
+end
+CODE
+</ruby>
+
+That’ll create +app/components+ directory and put +foo.rb+ in there.
+
+h4. rakefile(filename, data = nil, &block)
+
+Creates a new rake file under +lib/tasks+ with the supplied tasks :
+
+<ruby>
+rakefile("bootstrap.rake") do
+  <<-TASK
+    namespace :boot do
+      task :strap do
+        puts "i like boots!"
+      end
+    end
+  TASK
+end
+</ruby>
+
+The above creates +lib/tasks/bootstrap.rake+ with a +boot:strap+ rake task.
+
+h4. generate(what, args)
+
+Runs the supplied rails generator with given arguments. For example, I love to scaffold some whenever I’m playing with Rails :
+
+<ruby>
+generate(:scaffold, "person", "name:string", "address:text", "age:number")
+</ruby>
+
+h4. run(command)
+
+Executes an arbitrary command. Just like the backticks. Let's say you want to remove the +public/index.html+ file :
+
+<ruby>
+run "rm public/index.html"
+</ruby>
+
+h4. rake(command, options = {})
+
+Runs the supplied rake tasks in the Rails application. Let's say you want to migrate the database :
+
+<ruby>
+rake "db:migrate"
+</ruby>
+
+You can also run rake tasks with a different Rails environment :
+
+<ruby>
+rake "db:migrate", :env => 'production'
+</ruby>
+
+Or even use sudo :
+
+<ruby>
+rake "gems:install", :sudo => true
+</ruby>
+
+h4. route(routing_code)
+
+This adds a routing entry to the +config/routes.rb+ file. In above steps, we generated a person scaffold and also removed +public/index.html+. Now to make +PeopleController#index+ as the default page for the application :
+
+<ruby>
+route "map.root :controller => :person"
+</ruby>
+
+h4. inside(dir)
+
+I have my edge rails lying at +~/commit-rails/rails+. So every time i have to manually symlink edge from my new app. But now :
+
+<ruby>
+inside('vendor') do
+  run "ln -s ~/commit-rails/rails rails"
+end
+</ruby>
+
+So +inside()+ runs the command from the given directory.
+
+h4. ask(question)
+
++ask()+ gives you a chance to get some feedback from the user and use it in your templates. Lets say you want your user to name the new shiny library you’re adding :
+
+<ruby>
+lib_name = ask("What do you want to call the shiny library ?")
+lib_name << ".rb" unless lib_name.index(".rb")
+
+lib lib_name, <<-CODE
+class Shiny
+end
+CODE
+</ruby>
+
+h4. yes?(question) or no?(question)
+
+These methods let you ask questions from templates and decide the flow based on the user’s answer. Lets say you want to freeze rails only if the user want to :
+
+<ruby>
+rake("rails:freeze:gems") if yes?("Freeze rails gems ?")
+no?(question) acts just the opposite.
+</ruby>
+
+h4. git(:must => "-a love")
+
+Rails templates let you run any git command :
+
+<ruby>
+git :init
+git :add => "."
+git :commit => "-a -m 'Initial commit'"
+</ruby>
