 ## Introduction
 
-The **node-api-headers** moldule contains the header files for the C based 
-Node-API provided by Node.js.
+**node-api-headers** contains the header files for the C-based Node-API
+provided by Node.js. Node-API is an API for building native addons that
+guarantees the ABI (Application Binary Interface) stability across versions
+of Node.js (see: [Node-API](https://nodejs.org/dist/latest/docs/api/n-api.html)).
+
+Node-API headers are in the `include` folder. The Node-APIs that provide
+ECMAScript features from native code can be found in `js_native_api_types.h`
+and `js_native_api.h`. The APIs defined in these headers are included in
+`node_api_types.h` and `node_api.h`.
+The headers are structured in this way in order to allow implementations of
+Node-API outside of Node.js considering that for those implementations the
+Node.js specific APIs may not be applicable.
+
+**node-api-headers** is also a package published on **npm** that could be used
+in a process to compile and build native addons for Node.js.

+
+## Install
+
+```
+npm i node-api-headers
+```
+
+<a name="api"></a>
+
+## API
+
+The module exports two properties `include_dir` and `symbols`.
+### `include_dir`
+
+This property is a string that represents the include path for the Node-API
+headers.
+
+### `symbols`
+
+This property is an object that represents the symbols exported by Node-API
+grouped by version and api types.
+
+```js
+    V1: {
+        js_native_api_symbols: [
+            // List of symbols in js_native_api.h for the version 1.
+        ],
+        node_api_symbols: [
+          // List of symbols in node_api.h for the version 1
+        ]
+    },
+   // ...
+```
