+## QuickStart |快速入门
+
+The following is main codes for basic usage.
+
+``` C#
+// Load or install fonts(*.ttf) which are provided by yourself
+IFontRandomerFactory fontRandomerFactory = new ...;
+IFontRandomer fontRandomer = fontRandomerFactory.CreateFontRandomer();
+// Init color randomer
+IColorRandomer colorRandomer = new ...;
+IPainter painter = new Painter(fontRandomer, colorRandomer);
+// Init the content settings for images
+PainterOption painterOption = new(){...};
+// Optional. Generate random text for solid length
+ICodeTextGenerator codeTextGenerator = new ...;
+string codeText = codeTextGenerator.Generate(4);
+// Generate an image
+await painter.GenerateImageAsync(codeText, painterOption);
+```
