+This library contains an Open API v3 validator and an Azure Functions v4 hook that validates http function requests.
 
 It identifies the Azure function route and tries to find a matching route in the Open API specification. It then validates query parameters, 
 the request body and response body against the schema.
 
-(Note: This library does not validate the Open API specification itself. I suggest you use another tool for this for now.)
+## Caveats
+
+* Early version: Bugs most likely exist. Bug fixes welcome and more test cases very welcom. :-)
+* So far only tested with Open API specifications in v3
+* This library does not validate the Open API specification itself. I suggest you use another tool for this for now.
