title: How to set environment variables in fastlane?
body: <p>I had read the documents but I am still confused where to set the environment variables in the fastfile or the bash_profile. Can you please help me out with that?</p>
  
  <p>What I want to achieve is to set the apple developer credentials in fastfile and should not ask again if any user takes pull of my code and try to build it.</p>
  
  <p>I am writing this in fastlane file. Let me know if I am wrong.</p>
  
  <pre><code>default_platform(:ios)
  
  platform :ios do
  
  ENV["FASTLANE_DONT_STORE_PASSWORD"] = "1"
  ENV["FASTLANE_USER"] = ""
  ENV["FASTLANE_PASSWORD"] = ""
  
  desc "GENERATE SCREENSHOT"
  lane :Snaps do
  capture_screenshots
  end
  
  end
  </code></pre>
