 # serverless-aws-lambda-dynamic-trigger
 
 The plugin can register triggers (events) for a lambda function dynamically at the time of the deployment.
-1. It fetches the value of a parameter form the Parameter Store. The value must be a list ARNs separated by commas.
+The usual static trigger (event) definitions can be completely omitted.
+The original idea is to make the same lambda function triggered by different events on different environments (stages).
+This way we can even do some basic **feature switching**.

+## How it works
+The plugin when the host code gets deployed...
+1. Fetches the value of a defined parameter from the Parameter Store. The value must be a list ARNs separated by commas. (If there is only one trigger it's just a single ARN)
 2. Parses the individual ARNs and pulls out the name of the aws service.
-3. Register the ARNs as triggers with the configured lambda function or functions.
+3. Registers the ARNs as triggers with the configured lambda function or functions.
 
 Please note that you can only use the plugin with **sns**, **sqs** or **kinesis** triggers.

 This way we can switch features on and off on different stages.
