title: Where is config.php located in new ATK4-example install?
body: <p>I have just downloaded atk4-example and copied it to my Apache2 [webroot]
  I can access the ATK welcome page at: htp://[server]/atk4-example/</p>
  
  <p>I would like to set the DSN for MySQL in config.php, but I don't know where the file is</p>
  
  <p>I can see /[webroot]/atk4-example/config-default.php
  But there is no config.php</p>
  
  <p>There is a /[webroot]/atk4-example/atk4/tools/sampleproject/config.php
  But I assume this is unrelated sample code</p>
  
  <p>The documentation mentions config.php, but I don't think it actually says where it is</p>
  
  <p>Thanks for your help,</p>
  
  <p>Greg</p>
