+OpenHarmony 4.0 supports musl 1.2.3.
 
 ## Supported Capabilities
 OpenHarmony provides header files and library interfaces that are compatible (not fully compatible) with C99, C11, and POSIX, and supports Armv7-A, Arm64, and x86_64 architectures.

 ### Debugging Capabilities
-The libc provides dynamic settings of the basic log functions (disabled by default) for developers to view internal exceptions of the libc. You can set the **param** to enable or disable the log functions, without recompiling the libc. However, you are advised not to use the log functions in official release versions because they affect the running performance.
+The libc provides dynamic enabling of debug logging (disabled by default). The debug logs help you learn about exceptions of the libc. With this function, you only need to set **param**, which eliminates the need for rebuilding the libc. However, you are advised not to enable debug logging in official versions because it affects the running performance.
 
 #### 1. musl.log
-Set **musl.log.enable** to **true** to enable the **musl.log** function. To print other logs, you need to enable this function first.

-#### 2. Loader log function
-The loader starts applications and invokes dlopen() and dlclose() in libc. To view exceptions in the dynamic loading process, enable the loader log function.

+The loader starts applications and invokes **dlopen** and **dlclose** in the libc. To view exceptions during the loading process, you need to enable the loader logging function. The following describes common operations.
+* Enable the loader logging for all applications. Exercise caution when enabling this function because a large number of logs will be generated.
