-### Context-aware evaluation
-
-Sometimes the value of a flag must take into account some dynamic criteria about the application or user, such as the user location, IP, email address, or the location of the server.
-In OpenFeature, we refer to this as [`targeting`](https://openfeature.dev/specification/glossary#targeting).
-If the flag system you're using supports targeting, you can provide the input data using the `EvaluationContext`.

 ### Events
 
 Events allow you to react to state changes in the provider or underlying flag management system, such as flag definition changes, provider readiness, or error conditions.
