 If your project needs to be aware of the type of environment you're deployed to, you'll also be able to get `SERVERTYPE` (AWS Lambda), `FRAMEWORK` (Zappa), `PROJECT` (your project name) and `STAGE` (_dev_, _production_, etc.) variables at any time.
 
+Please note that these are not the [AWS Lambda environment variables](https://github.com/Miserlou/Zappa/issues/501) that Amazon now offers directly. These were implemented long before that feature was available, and will not be available through your AWS console.

 ##### Remote Environment Variables
 
 If you want to use remote environment variables to configure your application (which is especially useful for things like sensitive credentials), you can create a file and place it in an S3 bucket to which your Zappa application has access to. To do this, add the `remote_env` key to zappa_settings pointing to a file containing a flat JSON object, so that each key-value pair on the object will be set as an environment variable and value whenever a new lambda instance spins up.
