     The example shows several calls to `get_ref()`.
     
     ```cpp
-    --8<-- "examples/get_ref.cpp"

+    #include <nlohmann/json.hpp>
+    
+    using json = nlohmann::json;

+        json value = 17;
+    
+        // explicitly getting references
+        auto r1 = value.get_ref<const json::number_integer_t&>();
+        auto r2 = value.get_ref<json::number_integer_t&>();
