 The `make` command generates a lot of deprecation warnings during the compiling of the classes generated from the protobuf definitions. This is expected as the protobuf definitions contain `deprecated` flags for fields that will not be supported in future versions of the SDK.
 
+Build the SDK and generate a debian package using the `make` command below:
+
+```
+make -j6 install package
+```

 **On Windows:**
 
 - Open the `sln` file in the build folder in Microsoft Visual Studio.
