 Bundler specific tasks for Capistrano v3:
 
-   * cap production bundler:install
+```sh
+$ cap production bundler:install
+```
 
 It also prefixes certain binaries to use `bundle exec`.
 
 ## Installation
 
 Add these lines to your application's Gemfile:
 
-    gem 'capistrano', '~> 3.1'
-    gem 'capistrano-bundler', '~> 1.1.3'
+```ruby
+gem 'capistrano', '~> 3.1'
+gem 'capistrano-bundler', '~> 1.1.2'
+```
 
 And then execute:
 
-    $ bundle
+```sh
+$ bundle
+```
 
 Or install it yourself as:
 
-    $ gem install capistrano-bundler
+```sh
+$ gem install capistrano-bundler
+```
 
 ## Usage
 
 Require in `Capfile` to use the default task:
 
-    require 'capistrano/bundler'
+```ruby
+require 'capistrano/bundler'
+```
 
 The task will run before `deploy:updated` as part of Capistrano's default deploy, or can be run in isolation with `cap production bundler:install`

 You can parallelize the installation of gems with bundler's jobs feature.
 Choose a number less or equal than the number of cores your server.
 
-    set :bundle_jobs, 4 #This is only available for bundler 1.4+
+```ruby
+set :bundle_jobs, 4 # default: nil, only available for Bundler >= 1.4
+```
 
 This would execute the following bundle command on all servers
 (actual paths depend on the real deploy directory):
 
-    bundle install \
-      --binstubs /my_app/shared/bin \
-      --gemfile /my_app/releases/20130623094732/MyGemfile \
-      --path /my_app/shared/bundle \
-      --without development test \
-      --deployment --quiet
+```sh
+$ bundle install \
+  --binstubs /my_app/shared/bin \
+  --gemfile /my_app/releases/20130623094732/MyGemfile \
+  --path /my_app/shared/bundle \
+  --without development test \
+  --deployment --quiet
+```
 
 If any option is set to `nil` it will be excluded from the final bundle command.
