 ## Install
 
+To install the module, run the following command:
+
 ```bash
 go get github.com/iamando/welog
 ```
 
 ## Usage
 
+To use the module in your Go program, import it using the following code:
+
 ```go
 import "github.com/iamando/welog"
 ```
 
+Then, create a logger using the GenerateLogger function:
+
+```go
+logger := welog.GenerateLogger()
+```
+
+The **GenerateLogger** function takes a **LogLevel** parameter, which specifies the minimum log level to output. For example, if you set the log level to **Info**, the logger will output all log messages at the **Info**, **Warn**, and **Error** levels.
+
+Once you have a logger, you can use its methods to log messages at different levels:
+
+```go
+logger.Debug("Debug message")
+logger.Info("Info message")
+logger.Warn("Warn message")
+logger.Error("Error message")
+```
+
