title: Running Meteor Up how to choose settings file
body: <p>I am using Meteor Up to deploy my app to production server.</p>
  
  <p>For now I am configuring Meteor.settings through settings-dev.json and settings-prod.json for development and production environments.</p>
  
  <p>I have two main doubts:</p>
  
  <p>How can I run 'mup deploy' command from my machine and choose settings-prod.json?</p>
  
  <p>Is this the best practice to configure my server and resource values using settings-[env].json to deploy my app?</p>
  
  <p>Thanks</p>
