title: Where does composer install files to?
body: <p>Ok, so I am trying to learn composer. I installed composer using my server's SSH and ran this line:</p>
  
  <pre><code>php composer.phar require tomwalder/php-gds
  </code></pre>
  
  <p>And it did this:</p>
  
  <pre><code>Using version ^2.1 for tomwalder/php-gds
  ./composer.json has been created
  Loading composer repositories with package information
  Updating dependencies (including require-dev)
    - Installing tomwalder/php-gds (v2.1.0)
      Downloading: 100%         
  tomwalder/php-gds suggests installing google/apiclient (Allows you to use the JSON API Gateway/Datastore endpoints.
   Tested with 1.1.6)
  Writing lock file
  Generating autoload files
  </code></pre>
  
  <p>Great, so now I look on my webserver and nothing seems to have changed. No files appear to be there. Where does composer install the files to?</p>
