+Storing Directly into an Existing std::string Instance
+-----------------------------------------------------
+
+The simdjson library favours  the use of `std::string_view` instances because
+it tends to lead to better performance due to causing fewer memory allocations.
+However, they are cases where you need to store a string result in an `std::string``
+instance. You can do so with a version of the `to_string()` method which takes as
+a parameter a reference to an `std::string`.
+
+```C++
+  auto json = R"({
+  "name": "Daniel",
+  "age": 42
+})"_padded;
+  ondemand::parser parser;
+  ondemand::document doc = parser.iterate(json);
+  std::string name;
+  doc["name"].get_string(name);
+```
+
+The same routine can be written without exceptions handling:
+
+```C++
+  std::string name;
+  auto err = doc["name"].get_string(name);
+  if(err) { /* handle error */ }
+```
+
+The `std::string` instance, once created, is independent. Unlike our `std::string_view` instances, it does not point at data that is
+within our `parser` instance. The same caveat applies: you should
+only consume a JSON string once.
+
+You should be mindful of the trade-off: allocating multiple
+`std::string` instances can become expensive.
+
