 This is module to help you make web requests in Go, it is a wrapper around the standard library's `http` package.
 You can use Get or Post to make a request, and then use the `Response` object to get the response body, headers, status code, etc.
 
+### Example
+
+    package main
+
+    import (
+        "fmt"
+        "github.com/tonnytg/webreq"
+    )
+
+    func main() {
+        response, err := webreq.Get("https://api.example.com/data")
+        if err != nil {
+            fmt.Println("Error:", err)
+            return
+        }
+        fmt.Println("Response:", response)
+    }
+
+
 ## Why
 
 So many times I needed to make a request in an API and after convert body to struct, and every time I needed to configure http.Client and put headers and body. Thinking about "don't repeat your self" I believe this unified code can gain time build an easy way to make this request.
 
 What do you think? Liked, set star in this project to help me to help others!

+## Basic Usage
+
 ### Get
 
 Create a slice of headers to use and input in request 
 
-	headers := webreq.NewHeaders()
-	headers.Add("Content-Type", "application/json")
-
-	request := webreq.Builder("GET")
-	request.SetURL("https://610aa52552d56400176afebe.mockapi.io/api/v1/friendlist")
-
-	_, err := request.Execute()
-	if err != nil {
-		t.Error(err)
-	}
+    package main
+
+    import (
+        "fmt"
+        "github.com/tonnytg/webreq"
+    )
+
+    func main() {
+        response, err := webreq.Get("https://api.example.com/data")
+        if err != nil {
+            fmt.Println("Error:", err)
+            return
+        }
+        fmt.Println("Response:", response)
+    }
 
 
 ### Post
 
 Create a body data to send in request
 
-    ...
-	f := Friend{
-		CreatedAt:  time.Now(),
-		Name:       "Tonny",
-	}
-
-	// convert f to bytes
-	fBytes, err := json.Marshal(f)
-	if err != nil {
-		t.Error(err)
-	}
-
-	request := webreq.Builder("POST")
-	request.SetURL("https://610aa52552d56400176afebe.mockapi.io/api/v1/friendlist")
-	request.SetBody(fBytes)
-
-	body, err := request.Execute()
-	if err != nil {
-		t.Error(err)
-	}
-    ...
+    package main
 
+    import (
+        "fmt"
+        "github.com/tonnytg/webreq"
+    )
+
+    func main() {
+        data := map[string]string{"key": "value"}
+        response, err := webreq.Post("https://api.example.com/data", data)
+        if err != nil {
+            fmt.Println("Error:", err)
+            return
+        }
+        fmt.Println("Response:", response)
+    }
+        
+
+
+## Advange Usage
+
+
+### Custom Headers
+
+    headers := map[string]string{
+        "Content-Type": "application/json",
+        "Authorization": "Bearer your_token",
+    }
+
+    response, err := webreq.GetWithHeaders("https://api.example.com/data", headers)
+    if err != nil {
+        fmt.Println("Error:", err)
+        return
+    }
+    fmt.Println("Response:", response)
+
+
+
+### Erro Handlin
+
+    response, err := webreq.Get("https://api.example.com/data")
+    if err != nil {
+        switch err.(type) {
+        case webreq.HTTPError:
+            fmt.Println("HTTP error occurred:", err)
+        default:
+            fmt.Println("An error occurred:", err)
+        }
+        return
+    }
+    fmt.Println("Response:", response)
