title: amnah/yii2-user use own database instead of the migrated one
body: <p>Hiii,
  I'm starting to get familair with Yii 2.
  What i'm trying to do is instead of using the migrated database, use my own database. 
  Can someone tell me the best way to do that and where i should be looking.
  I'm using the basic template.</p>
  
  <p>Thanks in advance.</p>
