+## Logger structure
+
+```go
+var _ hlog.FullLogger = (*Logger)(nil)
+
+type Logger struct {
+    l   *slog.Logger
+    cfg *config
+}
+```
+
+## NewLogger
+
+Create and initialize a Logger through `defaultConfig()`. The required configuration can be passed into the function as a parameter. If no parameters are passed in, the initial configuration will be installed to create the Logger.
+For related configuration, please refer to [option configuration](#option-configuration) below
+
+Currently only `slog.NewJSONHandler()` in the slog library is supported, `slog.NewTextHandler()` is not supported
+
+Function Signature:
+
+```go
+func NewLogger(opts ...Option) *Logger
+```
+
+Sample code:
+
+```go
+package main
+
+import (
+    "github.com/cloudwego/hertz/pkg/common/hlog"
+    hertzslog "github.com/hertz-contrib/logger/slog"
+    "os"
+)
+
+func main() {
+    logger := hertzslog.NewLogger(hertzslog.WithOutput(os.Stdout))
+    hlog.SetLogger(logger)
+}
+```
+
+## Logger
+
+`Logger` is used to obtain `*slog.Logger` to meet complex operations
+
+Function Signature:
+
+```go
+func (l *Logger) Logger() *slog.Logger
+```
+
+Sample code:
+
+```go
+package main
+
+import (
+    hertzslog "github.com/hertz-contrib/logger/slog"
+    "os"
+)
+
+func main() {
+    logger := hertzslog.NewLogger(hertzslog.WithOutput(os.Stdout))
+    l := logger.Logger()
+}
+```
+
+## Option configuration
+
+### WithOutput
+
+`WithOutput` is used to set the output location of the log
+
+Function Signature:
+
+```go
+func WithOutput(writer io.Writer) Option
+```
+
+Sample code:
+
+```go
+package main
+
+import (
+    hertzslog "github.com/hertz-contrib/logger/slog"
+    "os"
+)
+
+func main() {
+    logger := hertzslog.NewLogger(hertzslog.WithOutput(os.Stdout))
+}
+
+
+```
+
+### WithLevel
+
+`WithLevel` judges the incoming `*slog.LevelVar`. Only log levels higher than or equal to this will be recorded
+
+>It is worth noting that if `WithLevel` is set together with `WithHandlerOptions`, the log level of WithLevel will override the log level in WithHandlerOptions
+
+Function Signature:
+
+```go
+func WithLevel(lvl *slog.LevelVar) Option
+```
+
+Sample code:
+
+```go
+package main
+
+import (
+    hertzslog "github.com/hertz-contrib/logger/slog"
+)
+
+func main() {
+    //Empty LevelVar corresponds to LevelInfo
+    logger := hertzslog.NewLogger(hertzslog.WithLevel(&slog.LevelVar{}))
+
+    //Dynamically set the log level to Level Debug
+    levelVar := slog.LevelVar{}
+    levelVar.Set(slog.LevelDebug)
+    logger := hertzslog.NewLogger(hertzslog.WithLevel(&slog.LevelVar{})) 
+}
+
+```
+
+### WithHandlerOptions
+
+`WithHandlerOptions` passes `*slog.HandlerOptions` into the configuration
+
+Function Signature:
+
+```go
+func WithHandlerOptions(opts *slog.HandlerOptions) Option 
+```
+
+Sample code:
+
+```go
+package main
+
+import (
+    hertzslog "github.com/hertz-contrib/logger/slog"
+)
+
+func main() {
+    logger := hertzslog.NewLogger(hertzslog.WithHandlerOptions(&slog.HandlerOptions{
+        AddSource:   false,
+        Level:       slog.LevelInfo,
+        ReplaceAttr: nil,
+    }))
+}
+```
+
+## A complete slog example
+
+```go
+package main

+func main() {

+		if _, err := os.Create(fileName); err != nil {
+			log.Println(err.Error())
+			return
+		}
+	}
+	
+	logger := hertzslog.NewLogger()
+	// set filename to date
+	lumberjackLogger := &lumberjack.Logger{
+        Filename:   fileName,
+        MaxSize:    20,   // A file can be up to 20M.
+        MaxBackups: 5,    // Save up to 5 files at the same time
+        MaxAge:     10,   // A file can be saved for up to 10 days.
+        Compress:   true, // Compress with gzip.
+	}
+
+	logger.SetOutput(lumberjackLogger)
+	logger.SetLevel(hlog.LevelDebug)
+
+	hlog.SetLogger(logger)
+
+	h.GET("/hello", func(ctx context.Context, c *app.RequestContext) {
+		hlog.Info("Hello, hertz")
+		c.String(consts.StatusOK, "Hello hertz!")
+	})
+
+	h.Spin()
+}
