 ### Installation
 ```bash
-go get github.com/guiferpa/gody@v1.1.0
+go get github.com/guiferpa/gody@v2.0.0
 ```
 
 ### Usage
 
 ```go
-package main
-
 import (
-	"log"
-
-	"github.com/guiferpa/gody"
-	"github.com/guiferpa/gody/rule"
+    "github.com/guiferpa/gody"
+    "github.com/guiferpa/gody/rule"
 )
 
-type Body struct {
-	Text string `json:"text" validate:"not_empty"`
+type RequestBody struct {
+    Name string `json:"name" validate:"not_empty"`
+    Age  int    `json:"age" validate:"min=21"`
 }
 
-func main() {
-	b := Body{}
+...
+
+validator := gody.NewValidator()
 
-	if validated, err := gody.Validate(b, nil); err != nil {
-		if !validated {
-			log.Println("body didn't validate:", err)
-		}
+rules := []gody.Rule{rule.NotEmpty, rule.Min}
+validator.AddRules(rules...)
 
-		switch err.(type) {
-		case *rule.ErrNotEmpty:
-			log.Println(err)
-		}
+func HTTPHandler(vtr *gody.Validator) http.HandlerFunc {
+    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+        var body RequestBody
+	if err := json.NewDecoder(r.Body).Decode(&body); err != nil {
+	    ...
 	}
+        defer r.Body.Close()
+
+        if validated, err := vtr.Validate(body); err != nil {
+            ...
+        }
+    }
 }
+
+port := /* port */
+http.ListenAndServe(port, HTTPHandler(validator))
+
+...

+### Others ways for validation
+
+There are others ways to valid a struct, take a look on functions below:
+
+- **RawValidate** - It's a function that make validate with no rule, it's necessary put the struct for validation, some rule(s) and tag name.
+
+```go
+gody.RawValidate(interface{}, string, []gody.Rule) (bool, error)
+```
+
+- **Validate** - It's a function that make validate with no rule, it's necessary put the struct for validation and some rule(s).
+```go
+gody.Validate(interface{}, []gody.Rule) (bool, error)
+```
+
+- **RawDefaultValidate** - It's a function that already have [built-in rules](https://github.com/guiferpa/gody/blob/72ce1caecc5fdacf40ee282716ec1b5abe6f7adf/validate.go#L15-L23) configured, it's necessary put the struct for validation, tag name and optional custom rule(s).
+```go
+gody.RawDefaultValidate(interface{}, string, []gody.Rule) (bool, error)
+```
+
+- **DefaultValidate** - It's a function that already have [built-in rules](https://github.com/guiferpa/gody/blob/72ce1caecc5fdacf40ee282716ec1b5abe6f7adf/validate.go#L15-L23) configured, it's necessary put the struct for validation and optional custom rule(s).
+```go
+gody.DefaultValidate(interface{}, []gody.Rule) (bool, error)
 ```

+1. At this time the only policy is don't create a Pull Request directly, it's necessary some discussions for some implementation then please open a issue before any thing to dicussion about the subject.
