+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+
+## 📦 Installation
+
+Install via NuGet Package Manager:
+
+```bash
+PM> Install-Package QRCoder
+```
+
+## 🚀 Quick Start
+
+Generate a QR code with just a few lines of code, either using a renderer's static helper method, or by creating a QR code first and then passing it to a renderer:
+
+```csharp
+using QRCoder;
+
+// Generate a simple black and white PNG QR code
+byte[] qrCodeImage = PngByteQRCodeHelper.GetQRCode("Hello World", QRCodeGenerator.ECCLevel.Q, 20);
+
+// Generate a scalable black and white SVG QR code
+using var qrCodeData = QRCodeGenerator.GenerateQrCode("Hello World", QRCodeGenerator.ECCLevel.Q);
+using var svgRenderer = new SvgQRCode(qrCodeData);
+string svg = svgRenderer.GetGraphic();
+```
+
+For more examples and detailed usage instructions, see: [Wiki: How to use QRCoder](https://github.com/Shane32/QRCoder/wiki/How-to-use-QRCoder)
+
+## 📱 Payload Generators
+
+QR codes can encode structured data that triggers specific actions when scanned (e.g., WiFi credentials, contact information, URLs). QRCoder includes payload generators that create properly formatted strings for these common use cases.
+
+### Usage Example
+
+```csharp
+using QRCoder;
+
+// Create a bookmark payload
+var bookmarkPayload = new PayloadGenerator.Bookmark("https://github.com/Shane32/QRCoder", "QRCoder Repository");
+
+// Generate the QR code data from the payload
+using var qrCodeData = QRCodeGenerator.GenerateQrCode(bookmarkPayload);
+
+// Or override the ECC level
+using var qrCodeData2 = QRCodeGenerator.GenerateQrCode(bookmarkPayload, QRCodeGenerator.ECCLevel.H);
+
+// Render the QR code
+using var pngRenderer = new PngByteQRCode(qrCodeData);
+byte[] qrCodeImage = pngRenderer.GetGraphic(20);
+```
+

+## 🔧 Advanced Features
+
+### Micro QR Codes
+
+QRCoder supports Micro QR codes, which are smaller versions of standard QR codes suitable for applications with limited space. Micro QR codes have significantly limited storage capacity—as few as 5 numeric digits (M1) or as many as 35 numeric digits (M4), with alphanumeric and byte data storing considerably less.
+
+```csharp
+using QRCoder;
+
+// Generate a Micro QR code (versions M1-M4, represented as -1 to -4)
+using var qrCodeData = QRCodeGenerator.GenerateMicroQrCode("Hello", QRCodeGenerator.ECCLevel.L, requestedVersion: -2);
+using var qrCode = new PngByteQRCode(qrCodeData);
+byte[] qrCodeImage = qrCode.GetGraphic(20);
+```
+
+**Note:** Micro QR codes have limitations on data capacity and error correction levels. They support versions M1 through M4 (specified as -1 to -4), and not all ECC levels are available for all versions. M1 only supports detection (no ECC), M2 and M3 support L and M levels, and M4 supports L, M, and Q levels. For detailed capacity tables, see the [Micro QR Code specification](https://www.qrcode.com/en/codes/microqr.html).
+
+### Working with QRCodeData
+
+`QRCodeData` is the core data structure that represents a QR code's module matrix. It contains a `List<BitArray>` called `ModuleMatrix`, where each `BitArray` represents a row of modules in the QR code. A module is set to `true` for dark/black modules and `false` for light/white modules.
+
+You can access the `ModuleMatrix` directly to read or manipulate the QR code data at the module level. This is useful for custom rendering implementations or analyzing QR code structure.
+
+```csharp
+using QRCoder;
+
+// Generate QR code data
+using var qrCodeData = QRCodeGenerator.GenerateQrCode("Hello World", QRCodeGenerator.ECCLevel.Q);
+
+// Access the module matrix
+var moduleMatrix = qrCodeData.ModuleMatrix;
+int size = moduleMatrix.Count; // Size of the QR code (includes quiet zone)
+
+// Manually render as ASCII (versus the included ASCII renderer)
+for (int y = 0; y < size; y++)
+{
+    for (int x = 0; x < size; x++)
+    {
+        // Check if module is dark (true) or light (false)
+        bool isDark = moduleMatrix[y][x];
+        Console.Write(isDark ? "██" : "  ");
+    }
+    Console.WriteLine();
+}
+```
