 For code safety, you should keep (1) the `parser` instance, (2) the input string and (3) the document instance alive throughout your parsing. Additionally, you should follow the following rules:

- By design, you should only have one `document` instance per JSON document. Thus, if you must pass a document instance to a function, you should avoid passing it by value: choose to pass it by reference instance to avoid the copy.

+- You will get better performance if you seek the keys in the order in which they appear in the document. So if processing `{"a":1, "b":2, "c":3}`, do `value1 = data["a"]; value2 = data["b"]; value3 data["c"];` and not `value2 = data["b"]; value1 = data["a"]; value3 data["c"];`. Of course, it is not always possible to know for sure in which order the keys appear.

+You can then parse the JSON document from the `simdjson::padded_string` instance:
+
+```cpp
+simdjson::dom::parser parser;
+simdjson::dom::element doc = parser.parse(my_padded_data);
+```
+
+Whenever you pass an `std::string` reference to `parser::parse`,
+the parser will access the bytes beyond the end of
+the string but before the end of the allocated memory (`std::string::capacity()`).
+If you are using a sanitizer that checks for reading uninitialized bytes or `std::string`'s
+container-overflow checks, you may encounter sanitizer warnings.
+You can safely ignore these warnings. Or you can call `simdjson::pad(std::string&)` to pad the
+string with `SIMDJSON_PADDING` spaces: this function returns a `simdjson::padding_string_view` which can be be passed to the parser's iterator function:
+
+```c++
+std::string json = "[1]";
+dom::element doc = parser.parse(simdjson::pad(json));
+```
+
 The parsed document resulting from the `parser.load` and `parser.parse` calls depends on the `parser` instance. Thus the `parser` instance must remain in scope. Furthermore, you must have at most one parsed document in play per `parser` instance.
 You cannot copy a `parser` instance, you may only move it.

+JSONPath
+------------
+
+
+The simdjson library supports a subset of [JSONPath](https://datatracker.ietf.org/doc/html/draft-normington-jsonpath-00) through the `at_path()` method, allowing you to reach further into the document in a single call. The subset of JSONPath that is implemented is the subset that is trivially convertible into the JSON Pointer format, using `.` to access a field and `[]` to access a specific index.
+
+Consider the following example:
+
+```c++
+auto cars_json = R"( [
+  { "make": "Toyota", "model": "Camry",  "year": 2018, "tire_pressure": [ 40.1, 39.9, 37.7, 40.4 ] },
+  { "make": "Kia",    "model": "Soul",   "year": 2012, "tire_pressure": [ 30.1, 31.0, 28.6, 28.7 ] },
+  { "make": "Toyota", "model": "Tercel", "year": 1999, "tire_pressure": [ 29.8, 30.0, 30.2, 30.5 ] }
+] )"_padded;
+dom::parser parser;
+dom::element doc;
+auto error = parser.parse(cars_json).get(doc);
+if(error) { /*won't happen*/ }
+double p;
+error = doc.at_path("[0].tire_pressure[1]").get(p);
+if(error) { /*won't happen*/ }
+cout << p << endl; // Prints 39.9
+```
+
+
+We also support the `$` prefix. When you start a JSONPath expression with $, you are indicating that the path starts from the root of the JSON document. E.g.,
+
+```c++
+auto json = R"( { "c" :{ "foo": { "a": [ 10, 20, 30 ] }}, "d": { "foo2": { "a": [ 10, 20, 30 ] }} , "e": 120 })"_padded;
+dom::parser parser;
+dom::element doc;
+auto error = parser.parse(json).get(doc);
+if(error) { /*won't happen*/ }
+dom::object obj;
+error = doc.get_object().get(obj);
+if(error) { /*won't happen*/ }
+int64_t x;
+error = obj.at_path("$[3].foo.a[1]").get(x);
+if(error) { /*won't happen*/ }
+if(x != 20) { /*won't happen*/ }
+x = obj.at_path("$.d.foo2.a.2");
+if(error) { /*won't happen*/ }
+```
