+# CSMatIO WPF Demo Application
+
+This is a .NET 8.0 WPF demo application for the CSMatIO library, which provides functionality for reading and writing MATLAB MAT-files in C#.
+
+## Features
+
+- Read MAT-files and display their contents
+- Create MAT-files with various data types:
+  - Cell arrays
+  - Structures
+  - Character arrays
+  - Sparse arrays
+  - Numeric arrays (Double, Single, Int8, UInt8, Int16, UInt16, Int32, UInt32, Int64, UInt64)
+  - Imaginary matrices
+
+## Requirements
+
+- .NET 8.0 SDK or later
+- Windows operating system
+
+## Building and Running
+
+1. Open the solution in Visual Studio 2022 or later
+2. Build the solution
+3. Run the CSMatIOTestWPF project
+
+## Usage
+
+1. To read a MAT-file, click the "Read MAT-File" button and select a file
+2. To create a MAT-file:
+   - Select the data types you want to include
+   - Click the "Create MAT-File" button
+   - Choose a location to save the file
+
+The output window will display information about the operations performed.
