 # Easy Sign
 
-Simple C# Library for signing and verifying files.
+Easy Sign is a simple C# library for signing and verifying files. It supports multiple .NET targets, including .NET Standard 2.1, .NET 6, and .NET 8.
+
+## Features
+
+- Sign files with X.509 certificates.
+- Verify file integrity and signatures.
+- Store files within the bundle.
+- Support for concurrent operations.
+
+## Installation
+
+To install Easy Sign, run the following command:
+
+
+```
+dotnet add package SAPTeam.EasySign
+
+```
+
+## Usage
+
+### Creating a Bundle
+
+
+```
+using SAPTeam.EasySign;
+
+// Initialize a new bundle
+var bundle = new Bundle("path/to/dir");
+
+// Add files to the bundle
+bundle.AddEntry("path/to/dir/file1.txt");
+bundle.AddEntry("path/to/dir/file2.txt");
+
+// Sign the bundle
+var certificate = new X509Certificate2("path/to/certificate.pfx", "password");
+var privateKey = certificate.GetRSAPrivateKey();
+bundle.Sign(certificate, privateKey);
+
+// Save the bundle
+bundle.Update();
+
+```
+
+### Loading and Verifying a Bundle
+
+
+```
+using SAPTeam.EasySign;
+
+// Load an existing bundle
+var bundle = new Bundle("path/to/dir");
+bundle.LoadFromFile();
+
+// Get certificate hash
+string certificateHash = bundle.Signatures.Entries.First().Key;
+
+// Verify certificate
+bool isCertificateValid = bundle.VerifyCertificate(certificateHash);
+
+// Verify signature
+bool isSignatureValid = bundle.VerifySignature(certificateHash);
+
+// Verify files integrity
+bool isFileValid = bundle.VerifyFileIntegrity("file1.txt");
+bool isFile2Valid = bundle.VerifyFileIntegrity("file2.txt");
+
+```
+
+## Command Line Interface
+
+Easy Sign also provides a command line interface (CLI) for signing and verifying files. To install the CLI tool, use the following command:
+
+
+```
+dotnet tool install -g SAPTeam.EasySign.Tool
+
+```
+

+Easy Sign CLI is a simple .NET tool for signing and verifying files. It supports multiple .NET targets, including .NET 6, .NET 8, and .NET 9.
+
+## Features
+
+- Create and update eSign bundles.
+- Sign bundles with X.509 certificates.
+- Verify file integrity and signatures within bundles.
+- Support for concurrent operations.
+
+## Installation
+
+To install the Easy Sign CLI tool, use the following command:
+
+
+```
+dotnet tool install -g SAPTeam.EasySign.Tool
+
+```
+
+## Usage
+
+### Commands
+
+#### `add`
+
+Creates a new bundle or updates an existing one by adding files from the specified directory.
+
+
+```
+esign add <directory> [-f <bundleFileName>]
+
+```
+
+- `directory`: The working directory containing the eSign bundle and files to be added to the bundle.
+- `-f`: (Optional) The name of the bundle file. Default is `.eSign`.
+
+#### `sign`
+
+Signs the bundle with a specified certificate.
+
+
+```
+esign sign <directory> [-f <bundleFileName>] [--pfx <pfxFilePath>] [--pfx-password <pfxFilePassword>] [--no-password]
+
+```
+
+- `directory`: The working directory containing the bundle to be signed.
+- `-f`: (Optional) The name of the bundle file. Default is `.eSign`.
+- `--pfx`: (Optional) The path to the PFX file containing the certificate and private key.
+- `--pfx-password`: (Optional) The password for the PFX file.
+- `--no-password`: (Optional) Ignore the PFX file password prompt.
+
+#### `verify`
+
+Verifies the file integrity and signatures of the bundle.
+
+
+```
+esign verify <directory> [-f <bundleFileName>]
+
+```
+
+- `directory`: The working directory containing the bundle to be verified.
+- `-f`: (Optional) The name of the bundle file. Default is `.eSign`.
+
+## Examples
+
+### Adding Files to a Bundle
+
+if there is no bundle file in the directory, a new bundle will be created. Otherwise, the files will be added to the existing bundle.
+
+
+```
+esign add /path/to/dir
+
+```
+
+### Signing a Bundle
+
+
+```
+esign sign /path/to/dir --pfx /path/to/certificate.pfx --pfx-password mypassword
