+This is a test app for iosAgent framework testing.
+
+- iOS version 13.0 or above is fully supported.
+- There is very limited support for iOS versions below 13.0. The main purpose is to test crash catching, make sure it's disabled.
+- If run on device, replace test bundle id com.instana.ios.InstanaAgentExample with a real one otherwise certain features like crash catching will not work.
