 ## Trigger
 
-The warmup trigger lets you define a function that will be run on an instance when it is added to your running app. You can use a warmup function to open connections, load dependencies, or run any other custom logic before your app will begin receiving traffic. 
+The warmup trigger lets you define a function that will be run on a new instance when it is added to your running app. You can use a warmup function to open connections, load dependencies, or run any other custom logic before your app will begin receiving traffic. 
 
 The warmup trigger is intended to create shared dependencies that will be used by the other functions in your app. [See examples of shared dependencies here](./manage-connections.md#client-code-examples).
 
-Note that the warmup trigger is only called during scale-up operations, not during restarts or other non-scale startups. You must ensure your logic can load all necessary dependencies without using the warmup trigger. Lazy loading is a good pattern to achieve this.
