+## Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.

+### Nan::NewBuffer()
+
+Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
+
+Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
+When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
+You _must not_ free the memory space manually once you have created a `Buffer` in this way.

+### Nan::CopyBuffer()
+
+Similar to [`Nan::NewBuffer()`](#api_nan_new_buffer) except that an implicit memcpy will occur within Node. Calls `node::Buffer::Copy()`.
+
+Management of the `char*` is left to the user, you should manually free the memory space if necessary as the new `Buffer` will have its own copy.

+```c++
+Nan::MaybeLocal<v8::Object> Nan::CopyBuffer(const char *data, uint32_t size)

+<a name="api_nan_free_callback"></a>
+### Nan::FreeCallback()
+
+A free callback that can be provided to [`Nan::NewBuffer()`](#api_nan_new_buffer).
+The supplied callback will be invoked when the `Buffer` undergoes garbage collection.
+
+Signature:
+
+```c++
+typedef void (*FreeCallback)(char *data, void *hint);
+```
