 \* Indicates that the N-API version was released as experimental
 
+The N-APIs associated strictly with accessing ECMAScript features from native
+code can be found separately in `js_native_api.h` and `js_native_api_types.h`.
+The APIs defined in these headers are included in `node_api.h` and
+`node_api_types.h`. The headers are structured in this way in order to allow
+implementations of N-API outside of Node.js. For those implementations the
+Node.js specific APIs may not be applicable.
+
+The Node.js-specific parts of an addon can be separated from the code that
+exposes the actual functionality to the JavaScript environment so that the
+latter may be used with multiple implementations of N-API. In the example below,
+`addon.c` and `addon.h` refer only to `js_native_api.h`. This ensures that
+`addon.c` can be reused to compile against either the Node.js implementation of
+N-API or any implementation of N-API outside of Node.js.
+
+`addon_node.c` is a separate file that contains the Node.js specific entry point
+to the addon and which instantiates the addon by calling into `addon.c` when the
+addon is loaded into a Node.js environment.

+```C
+// addon.h
+#ifndef _ADDON_H_
+#define _ADDON_H_
+#include <js_native_api.h>
