+### Nan::AsyncResource
+
+This class is analogous to the `AsyncResource` JavaScript class exposed by Node's [async_hooks][] API.
+
+When calling back into JavaScript asynchronously, special care must be taken to ensure that the runtime can properly track
+async hops. `Nan::AsyncResource` is a class that provides an RAII wrapper around `node::EmitAsyncInit`, `node::EmitAsyncDestroy`,
+and `node::MakeCallback`. Using this mechanism to call back into JavaScript, as opposed to `Nan::MakeCallback` or
+`v8::Function::Call` ensures that the callback is executed in the correct async context. This ensures that async mechanisms
+such as domains and [async_hooks][] function correctly.
+
+Definition:
+
+```c++
+class AsyncResource {
+ public:
+  AsyncResource(v8::Local<v8::String> name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  AsyncResource(const char* name,
+                v8::Local<v8::Object> resource = New<v8::Object>());
+  ~AsyncResource();
+
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::Function> func,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            v8::Local<v8::String> symbol,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+  v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+                                            const char* method,
+                                            int argc,
+                                            v8::Local<v8::Value>* argv);
+};
+```
+
+* `name`: Identifier for the kind of resource that is being provided for diagnostics information exposed by the [async_hooks][]
+  API. This will be passed to the possible `init` hook as the `type`. To avoid name collisions with other modules we recommend
+  that the name include the name of the owning module as a prefix. For example `mysql` module could use something like
+  `mysql:batch-db-query-resource`.
+* `resource`: An optional object associated with the async work that will be passed to the possible [async_hooks][]
+  `init` hook. If this parameter is omitted, or an empty handle is provided, this object will be created automatically.
+* When calling JS on behalf of this resource, one can use `runInAsyncScope`. This will ensure that the callback runs in the
+  correct async execution context.
+* `AsyncDestroy` is automatically called when an AsyncResource object is destroyed.
+
+For more details, see the Node [async_hooks][] documentation. You might also want to take a look at the documentation for the
+[N-API counterpart][napi]. For example usage, see the `asyncresource.cpp` example in the `test/cpp` directory.
+
+<a name="api_nan_make_callback"></a>
+### Nan::MakeCallback()
+
+Deprecated wrappers around the legacy `node::MakeCallback()` APIs. Node.js 10+
+has deprecated these legacy APIs as they do not provide a mechanism to preserve
+async context.
+
+We recommend that you use the `AsyncResource` class and `AsyncResource::runInAsyncScope` instead of using `Nan::MakeCallback` or
+`v8::Function#Call()` directly. `AsyncResource` properly takes care of running the callback in the correct async execution
+context – something that is essential for functionality like domains, async_hooks and async debugging.

+### NAN_MODULE_INIT()
+
+Used to define the entry point function to a Node add-on. Creates a function with a given `name` that receives a `target` object representing the equivalent of the JavaScript `exports` object.
+
+See example below.
+
+<a name="api_nan_export"></a>
+### Nan::Export()
+
+A simple helper to register a `v8::FunctionTemplate` from a JavaScript-accessible method (see [Methods](./methods.md)) as a property on an object. Can be used in a way similar to assigning properties to `module.exports` in JavaScript.
+
+Signature:
+
+```c++
+void Export(v8::Local<v8::Object> target, const char *name, Nan::FunctionCallback f)
+```
+
+Also available as the shortcut `NAN_EXPORT` macro.
+
+Example:
+
+```c++
+NAN_METHOD(Foo) {
+  ...
+}
+
+NAN_MODULE_INIT(Init) {
+  NAN_EXPORT(target, Foo);
+}
+```
