 The preferred way is to use a configuration file that specifies information about all Lambda@Edge functions for a specific CloudFront distribution.
 Even if there is only one Lambda@Edge function attached to the distribution, the configuration file can simplify the commands considerably.
 
+**Note:** If your S3 bucket used to store the Lambda ZIP files is in a different AWS region than where the base Lambda functions
+are deployed, replace `awsRegion` with `s3Region` and `lambdaRegion`. This might be the case if your company has strict security
+or compliance requirements.

 Start with this configuration file template and modify to fit your needs (triggers can be removed if not used):

 - `--pwd`: Sets the present working directory. All relative paths (for config file and local file path) will resolve from this value. Defaults to `process.cwd()`
-- `--region`: Sets the AWS region. Defaults to `'us-east-1'`
+- `--region`: Sets the AWS region for both S3 and Lambda. Defaults to `'us-east-1'`
