-# IRext decode algorithm porting examples
+# IRext Win32 Example
 
-This repository contails various of example which show you how to port IRext decode algorithm to different OS and platforms
+A Windows desktop example demonstrating the IRext infrared decoder library.
 
-Version 1.5.0
+## Overview
 
-- Android example
-- Java web example with JNI
-- Windows example
-- Arduino example (TBD)
+IRext is an open-source infrared remote control library. This example provides a command-line application to test IR decoding functionality on Windows.
+
+## Features
+
+- Decode IR binary files for air conditioners (AC)
+- Decode IR binary files for TV devices
+- Query supported AC modes, wind speeds, swing options, and temperature ranges
+- Generate IR timing data for remote control signals
+
+## Requirements
+
+- Operating System: Windows 10 or later
+- IDE: Visual Studio 2019 or later
+- Build Tools: MSVC v142 (VS2019) or v143 (VS2022)
+
+## Building
+
+1. Open win32-example/IRextWin32Example.sln in Visual Studio.
+
+2. If you encounter build error MSB8020 (Platform Toolset not found), retarget the solution:
+   - Right-click the solution in Solution Explorer
+   - Select Retarget solution
+   - Choose an installed Windows SDK and Platform Toolset
+
+3. Select the desired configuration (Debug or Release) and platform (x86 or x64).
+
+4. Build the solution (Ctrl+Shift+B or Build > Build Solution).
+
+## Usage
+
+1. Run the compiled executable from the command line.
+2. The program will prompt you to input key codes to simulate remote control actions.
+3. Key code reference: https://site.irext.net/doc#keymap
+4. Enter 99 to exit the program.
+
+### Example Key Codes
+
+| Key Code | Function |
+|----------|----------|
+| 14 | Query supported modes |
+| 15 | Query supported wind speeds |
+| 16 | Query temperature range |
+| 99 | Exit program |
