 ## Features
 
-- [x] Creates AWS EventBridge Resources
+- [x] Creates AWS EventBridge Resources (bus, rules, targets, permissions)
+- [x] Attach resources to an existing EventBridge bus
 - [x] Support AWS EventBridge Archives and Replays
 - [x] Conditional creation for many types of resources
 - [x] Support IAM policy attachments and various ways to create and attach additional policies
 - [ ] Support monitoring usage with Cloudwatch Metrics
