-## Introduction
-
-Welcome to the documentation for **inxy-payments/signature-sdk-go**! This library is designed to help you sign messages using a private key. Whether you're a beginner or an experienced developer, this guide will help you get the most out of this library.
+The `signature-sdk-go` package provides functionality for signing messages using RSA private keys and verifying signatures using the corresponding RSA public keys. This package is useful for ensuring the integrity and authenticity of messages in your Go applications.
 
 ## Installation
+
+To use this package, you need to have Go installed. You can download it from [golang.org](https://golang.org/dl/).
+
+To include this package in your project, run:
+
+```sh
+go get github.com/inxy-payments/signature-sdk-go
+```
+
+## Usage
+Below is an example of how to use the signature-sdk-go package to sign a message and verify the signature.
+
+## Example
+
+```go
+package main
+
+import (
+	"fmt"
+	"github.com/inxy-payments/signature-sdk-go/pkg/converter"
+	"github.com/inxy-payments/signature-sdk-go/pkg/model"
+	rsaSignatureService "github.com/inxy-payments/signature-sdk-go/pkg/service/rsa"
+	"log"
+)
+
+func main() {
+	const privateKeyExample = "MIIEowIBAAKCAQEAviXbecnlVp3qPbTAREhr5t8mDTLjJD3cE5SI8LsIjE2wbs23nkCYe47HveFJf+yqD1FqAaDYi+svRsPqVKVD/3HcAkx+Qn1cPQyVmFrbj0Q5U6vP7EuVi4ICG3BX5+l5DCAp5uIcLP9sr9h+4KxaMGaztYzutHjfsZRX99AwLJfw5axVyGIhZb3fZ1YyeI/P2AGQn8iY2XZQGYwc8emyqh3B0zByKLSMuuRDu20jZYXTrWDf+uZDSjZoqcXKmZfJIWxuufICa1H1xIxCxPjV91zG6AKPsqA74TbO91nZGE1yhPE/BA8dkgE+1NEQDWYNMs8cFqQLrLouRqY+g+HVzQIDAQABAoIBADXD+JooR2vFfS1zhYYJQFFouZaz09w0jZ0Pu+Ttzc32TbQXARuDQlp1le8P27uLTM7GA4ZwV6rAln6Y+RJ0JJT/OemAfZcJYWJ1w3rv/fM1pEwPYdx7xs5KtZPSoViXAL43/gEl4DetBat3OPEIavwSni/wqLJpFz9cJb+Ro32H//TECzivHvSxDDUrhMDTQHQeBw7ATiIVNT2iPutprKqjMNga4cg/vxm5BgiMTMjo2adbKQPKa4k5q3YOuFrkacjwbuRBpZtnqWd568moERMym8iHrdsUI/tgprQI7wxev/gj+nk5cbZoEr0fBvoTH/HDna3G5rGOE5uti5adn6ECgYEA6xvoG961ovmZinScEOx/xcrWT2Q1TuazOQesPf0ywfT/BAUCqxVQeEVHV78089HSP5QHHes5iq+MFAL8/hGlPq0EoHDDE1hyxS0gbZcR6oEmRKyOfSbShGn22Cuw0JWt7rOHzdHj8KCpZgpXLJUyKL0Tx2vCKaM3zb7lOFkIshkCgYEAzws06a5LJY4cuKjZkwews0MxCm7SpQXuoSnkOo1ROLukgJ209Le5IdNYC47GYDcwhkuY4tSRxyfq7rd4Upui9XjkaqiblpqOVcdajAI8XgmCbzwxaUcvomQpvC8lFocoOGtAw2P8TZ3WGOb3GoF/o1pQ0Dh9HLOrAPo79RONv9UCgYEA0s7L+SlhPgeF17KlOTuFecldDgSxE9UhwDIUC+Ua/PR7MJR5hwNuiti7ln8YsMJjPaSyGO6QQr0S4eKoC/uwahli+6UAFTmKdyf2Wq1JYDZ7JLqAbNFBk38b2UqbmPuM4GpTi4X2Vw0HtznwXkZMmmCm+nmxt/nkkHPpPfP/KwkCgYBQDphGJ2PdQKcwa/G9XYLgvgFvdEy1DKcp4CXk0hHu6vd/1/tJiOToBG2OAoYIXC7CLucOBn3b0T6RUZYP8yg+3KEN8OZAhMC2wF/ttUucXPb3hgHhIGp1018j6eLgZCCUODyRkM7VQEux01UHBb3R7zFCYiVWfM6JkTiv2gC8hQKBgHHFdpHeTu0vJf480UHd8e0vLfpRPqWhAaZBHRtY05Hv9/ClGR8sZ471e1Nk3LJNmOzzL/HN89oD8gHSJGmqHjmbUwpIQK8zCCpuwzAjbdghaHgupss4TJApnS8HuybW+eGBu/AIUlJqOCCImfoB5Gurk5VsjEpo2+lWIFKEJrlG"
