+# File Renamer Tool
+
+## Overview
+The File Renamer Tool is a command-line application written in C# designed to rename files in a specified directory based on a customizable naming format. It allows users to filter files by extension, define a custom file naming format, and specify a starting number for file naming counters. This tool is particularly useful for organizing collections of files, such as photos or documents, by renaming them according to a consistent pattern.
+
+## Features
+- **Custom File Naming**: Specify a custom naming format for the files using placeholders.
+- **Extension Filtering**: Rename only files of a specific extension within the directory.
+- **Counter Start Point**: Begin the naming sequence from a custom starting number.
+- **Help Guide**: Access a help guide with usage instructions directly from the command line.
+
+## Usage
+
+### Prerequisites
+- .NET Runtime environment
+- Command line or terminal access
+
+### Running the Tool
+1. Open your command line or terminal.
+2. Navigate to the directory where the File Renamer Tool is located.
+3. Execute the tool using the following syntax:
+
+```shell
+File_Renamer [options]
+--help, -h: Show the help message with usage instructions.
+path=YourFolderPath: Specify the folder path containing the files you wish to rename.
+extension=YourExtension: Specify the file extension of the files you wish to rename (default: .png).
+format=YourFormat: Specify the file name format. Use {counter} as a placeholder for the numbering (default: {counter}).
+start=YourStartNumber: Specify the starting number for the counter (default: 1).
+```
+
+### Examples
+Rename .png files in the C:\Users\Example\Pictures directory using the default naming format starting from 100:
+
+```shell
+File_Renamer path=C:\Users\Example\Pictures extension=png start=100
+```
+
+Rename files in the C:\Documents directory with a custom format and extension:
+
+```shell
+File_Renamer path=C:\Documents extension=txt format=Document_{counter} start=1
+```
