 # Setup REST and MQTT
+
+
+
+* 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\_test_sdp.git
+
+<img src = './assets/img_1.png'>
+
+
+* Otherwise, take care to import the project as a Gradle Project
+
+## REST
+
+* Run StartServer.java located in: *REST\_MQTT_example/src/main/java/REST/*
+* Use a REST Client application (i.e., Advanced REST Client) to test if the server works correctly
+* For example you can run the following request:

+<img src = './assets/img_2.jpeg'>
+
+
+## MQTT
+* Dowload and install the Mosquitto broker from here: *https://mosquitto.org/download/*
+* Run the Mosquitto broker:
+	* **MacOS**
+		- brew services start mosquitto
+		- mosquitto_sub -h localhost -v -t ‘#’  *(Instead ‘#’ specify the topics of interest)*
+	* **Windows**
