-# Setup ProtocolBuffer and GRPC
-This repository contains a simple example that enables you to test the environment for **ProtocolBuffer** and **GRPC**.
+# Lab3 Examples
 
-* You can import the project directly from a **V**ersion **C**ontrol **S**ystem, by providing the following URL: 
-https://ewserver.di.unimi.it/gitlab/riccardopresotto/setup_grpc.git
-
-<img src = './assets/img_1.png'>
-
-* Otherwise, take care to import the project as a Gradle Project
-
-* Compile the .proto files: 
-	1.  Open the terminal of the IntelliJ IDE
-	2. Run the following command:
-		* **Windows**: *gradlew build*
-		* **MacOS/Linux**: *./gradlew build*
-	3. Check if some files have been generated in the directory *setup_grpc/build/generated/source/proto/main/java*
-
-* The testing files are located in the directory: *setup_grpc/src/main/java/researcher*
+* Protocol Buffers
 
+* GRPC
