 # is
 
-Package is includes validation functions of various data such as e-mail, bank card number, bank account IBAN, phone number and others.
+Is package provides various validation functions to check the correctness of different types of data. It offers a collection of functions to validate data such as numbers, strings, geographic coordinates, email addresses, e-mail, bank card number, bank account IBAN, phone and more.
 
-The package provides validation functions that do not pre-clean the data. If the validation data needs to be cleaned, it must be cleaned beforehand,
-for example using the g package.
+## Note
 
+The package provides validation functions that do not pre-clean the data. If the validation data needs to be cleaned, it must be cleaned beforehand, for example, using the [g package](https://github.com/goloop/g), as `g.Weed`, `g.Trim` etc.
+
+
+## Installation
+
+To use the Go Is package in your project, you need to install it using the go get command:
+
+```shell
+go get github.com/goloop/is
+```
+
+## Usage
+
+Here's an example of how to use the Go Is package to validate different types of data:
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/goloop/is"
+)
+
+func main() {
+	// Validate a phone number
+	phoneNum := "+3 (8096) 46 200 00"
+	if is.Phone(phoneNum) {
+		fmt.Println("Valid phone number")
+	} else {
+		fmt.Println("Invalid phone number")
+	}
+
+	// Validate an email address
+	email := "[email protected]"
+	if is.Email(email) {
+		fmt.Println("Valid email address")
+	} else {
+		fmt.Println("Invalid email address")
+	}
+
+	// Validate geographic coordinates
+	latitude := 37.7749
+	longitude := -122.4194
+	if is.Coordinates(latitude, longitude) {
+		fmt.Println("Valid coordinates")
+	} else {
+		fmt.Println("Invalid coordinates")
+	}
+}
+```
+
+This example demonstrates how to use the Go Is package to validate a phone number, email address, and geographic coordinates. You can import the github.com/goloop/is package and call the corresponding validation functions for the specific data you want to validate. The functions will return a boolean value indicating whether the data is valid or not.
