title: How to permit access to my config.yaml file? (Raspbian, Azure IoT Edge)
body: <p>I've been going through the Azure IoT Edge documentation to connect a Raspberry Pi 4 using Raspbian Stretch to the Azure Cloud. The IoT Edge daemon is 'active (running)' but when I run 'iotedge check' I get the following error:</p>
  <pre><code>pi@raspberrypi:~$iotedge check --verbose
  Configuration checks
  --------------------
  x config.yaml is well-formed - Error
     Could not open file /etc/iotedge/config.yaml. You might need to run this command as a root.
         caused by: Permission denied (os error 13)
  
  0 check(s) succeeded.
  1 check(s) raised errors.
  
  </code></pre>
  <p>I am fairly new to this so may have made an obvious error but can't find anything on google, Azure or Stack Overflow that applies. Any help would be much appreciated!</p>
