 You can import the native .so that contains the JS processing logic. For example, **import hello from 'libhello.so'** to use the **libhello.so** capability. Then, the JS object created using the NAPI can be passed to the **hello** object of the application to call the native capability.

 ### .so Naming Rules
 
-Each module has a .so file. For example, if the module name is **hello**, name the .so file **libhello.so**. The **nm_modname** field in **napi_module** must be **hello**, which is the same as the module name. The sample code for importing the .so file is **import hello from 'libhello.so'**.
+The .so file names must comply with the following rules:
