 ### Adding New CLI Options
-1. Update `src/Refitter/GenerateCommand.cs` with new command-line arguments
-2. Add corresponding property to `src/Refitter.Core/Settings/RefitGeneratorSettings.cs`
-3. Implement logic in `src/Refitter.Core/RefitInterfaceGenerator.cs`
-4. Add unit tests in `src/Refitter.Tests/Examples/`
-5. Update README.md documentation
+1. Add new property to `src/Refitter/Settings.cs` with `[CommandOption("--option-name")]` attribute
+2. Update `CreateRefitGeneratorSettings()` method in `src/Refitter/GenerateCommand.cs` to map the setting
+3. Add corresponding property to `src/Refitter.Core/Settings/RefitGeneratorSettings.cs`
+4. Implement logic in `src/Refitter.Core/RefitInterfaceGenerator.cs` or related generator classes
+5. Add unit tests in `src/Refitter.Tests/Examples/` following the established pattern
+6. Update README.md documentation with the new option

+### Simple Output Mode
+
+For integration with IDEs and build tools that don't support rich console formatting, Refitter provides a `--simple-output` option:
+
+```shell
+refitter ./openapi.json --simple-output
+```
+
+This mode generates plain text output without:
+
+- ASCII art and banners
+- Colored text and rich formatting
+- Unicode characters and emojis
+- Tables and panels
+
+This is particularly useful when:
+
+- Running Refitter from Visual Studio extensions
+- Integrating with build systems that capture console output
+- Using tools that don't support ANSI escape sequences
+- Running in environments with limited console capabilities
+
 ## Source Generator
 
 Refitter is available as a C# Source Generator that uses the [Refitter.Core](https://github.com/christianhelle/refitter/tree/main/src/Refitter.Core) library for generating a REST API Client using the [Refit](https://github.com/reactiveui/refit) library. Refitter can generate the Refit interface from OpenAPI specifications. Refitter could format the generated Refit interface to be managed by [Apizr](https://www.apizr.net) and generate some registration helpers too.
