+This package contains basic examples for jvpp. To run the examples:
+
+- Make sure VPP is running
+- From VPP's build-root/ folder execute:
+  - release version: sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-18.01.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-18.01.jar io.fd.vpp.jvpp.core.examples.[test name]
+  - debug version: sudo java -cp build-vpp_debug-native/vpp/vpp-api/java/jvpp-registry-18.01.jar:build-vpp_debug-native/vpp/vpp-api/java/jvpp-core-18.01.jar io.fd.vpp.jvpp.core.examples.[test name]
+
+Available examples:
+CallbackApiExample - Similar to ControlPingTest, invokes more complex calls (e.g. interface dump) using low level JVpp APIs
+CallbackJVppFacadeNotificationExample - Example of interface notifications using Callback based JVpp facade
+CallbackJVppFacadeExample - Execution of more complex calls using Callback based JVpp facade
+CallbackNotificationApiExample -  Example of interface notifications using low level JVpp APIs
+CreateSubInterfaceExample - Example of sub-interface creation
+FutureApiNotificationExample - Example of interface notifications using Future based JVpp facade
+FutureApiExample - Execution of more complex calls using Future based JVpp facade
+L2AclExample - Example of L2 ACL creation
+LispAdjacencyExample - Example of lisp adjacency creation and read (custom vpe.api type support showcase)
+
+CallbackApiReadPerfTest, FutureApiReadPerfTest, CallbackApiWritePerfTest - test provide two ways to count invocations:
+1) maximum number of invocations and received replyies within 1 sec
+sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-18.01.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-18.01.jar io.fd.vpp.jvpp.core.examples.[test name]
+2) measure time in ns from first request to receiving last reply over set amount of requests
+sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-18.01.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-18.01.jar io.fd.vpp.jvpp.core.examples.[test name] [number of request to send]

+This package contains basic tests for jvpp. To run the tests:
+
+- Make sure VPP is running
+- From VPP's build-root/ folder execute:
+  - release version: sudo java -cp build-vpp-native/vpp/vpp-api/java/jvpp-registry-17.10.jar:build-vpp-native/vpp/vpp-api/java/jvpp-core-17.10.jar io.fd.vpp.jvpp.core.test.[test name]
+  - debug version: sudo java -cp build-vpp_debug-native/vpp/vpp-api/java/jvpp-registry-17.10.jar:build-vpp_debug-native/vpp/vpp-api/java/jvpp-core-17.10.jar io.fd.vpp.jvpp.core.test.[test name]
+
+Available tests:
+CallbackApiTest - Similar to ControlPingTest, invokes more complex calls (e.g. interface dump) using low level JVpp APIs
+CallbackJVppFacadeNotificationTest - Tests interface notifications using Callback based JVpp facade
+CallbackJVppFacadeTest - Execution of more complex calls using Callback based JVpp facade
+CallbackNotificationApiTest - Tests interface notifications using low level JVpp APIs
+ControlPingTest - Simple test executing a single control ping using low level JVpp APIs
+CreateSubInterfaceTest - Tests sub-interface creation
+FutureApiNotificationTest - Tests interface notifications using Future based JVpp facade
+FutureApiTest - Execution of more complex calls using Future based JVpp facade
+L2AclTest - Tests L2 ACL creation
+LispAdjacencyTest - Tests lisp adjacency creation and read (custom vpe.api type support showcase)
