 ## Introduction
 
-Node-API provides APIs to encapsulate JavaScript capabilities as a native plug-in. It is independent of the underlying JavaScript and is maintained as part of Node.js.
+Node-API (NAPI) provides APIs to encapsulate JavaScript capabilities as a native plug-in. It is independent of the underlying JavaScript and is maintained as part of Node.js.
 
 
 ## Supported Capabilities
 
-Node-API eliminates the differences between underlying JavaScript engines and provides a set of stable interfaces.
+NAPI eliminates the differences between underlying JavaScript engines and provides a set of stable interfaces.
 
-The OpenHarmony Native API (NAPI) component optimizes the Node-API interface implementation and provides connection to underlying engines such as ArkJS. Currently, some APIs in the [Node-API](https://nodejs.org/docs/v14.9.0/api/n-api.html) standard library are supported.
