 ## Usage
 
-Require in `Capfile` to use the default task:
+Require the module in your `Capfile`:
 
 ```ruby
 require 'capistrano/composer'
 ```
 
-The task will run before `deploy:updated` as part of Capistrano's default deploy,
-or can be run in isolation with `cap production composer:install`
+`capistrano/composer` comes with 5 tasks:
+
+* composer:install
+* composer:install_executable
+* composer:dump_autoload
+* composer:self_update
+* composer:run
+
+The `composer:install` task will run before deploy:updated as part of
+Capistrano's default deploy, or can be run in isolation with:
+
+```bash
+$ cap production composer:install
+```
+
+By default it is assumed that you have the composer executable installed and in your
+`$PATH` on all target hosts.
+
+### Configuration
 
 Configurable options, shown here with defaults:
 
 ```ruby
-set :composer_flags, '--production --silent'
+set :composer_install_flags, '--no-dev --no-scripts --quiet --optimize-autoloader'
 set :composer_roles, :all
+set :composer_dump_autoload_flags, '--optimize'
+set :composer_download_url, "https://getcomposer.org/installer"
+```
+
+### Installing composer as part of a deployment
+
+Add the following to `deploy.rb` to manage the installation of composer during
+deployment (composer.phar is install in the shared path).
+
+```ruby
+SSHKit.config.command_map[:composer] = "#{shared_path.join("composer.phar")}"
+
+namespace :deploy do
+  before :starting, 'composer:install_executable'
+end
+```
+
+### Accessing composer commands directly
+
+This library also provides a `composer:run` task which allows access to any
+composer command.
+
+From the command line you can run
+
+```bash
+$ cap production composer:run['status','--profile']
 ```
 
+Or from within a rake task using capistrano's `invoke`
+
+```ruby
+task :my_custom_composer_task do
+  invoke "composer:run", :update, "--dev --prefer-dist"
+end
+```
