 The themes based on the original sinks are slightly adjusted to be [WCAG compliant](https://www.w3.org/WAI/WCAG22/Understanding/contrast-minimum), ensuring that the contrast ratio between text and background colors is at least 4.5:1.
 
 You can create your own custom themes by creating a new instance of the [Theme](Serilog.Sinks.RichTextBox.WinForms.Colored/Sinks/RichTextBoxForms/Themes/Theme.cs) class and passing it to the `RichTextBox` extension method. Look at the [existing themes](Serilog.Sinks.RichTextBox.WinForms.Colored/Sinks/RichTextBoxForms/Themes/ThemePresets.cs) for examples.
 
-## Frequently Asked Questions
-
-### Why is the package name so long?
+## Support the Project 💖
 
-Shorter alternatives were already reserved in the NuGet registry, so a more descriptive name was needed for this implementation. The name is a bit long, but it makes it easier to find the package in the NuGet registry.
+This project has been maintained since 2022 and is still under active development. If you find it useful, please consider supporting it. Your support will help keep the project alive and allow me to dedicate more time to making improvements. You can support it through:
 
-### Why use a WinForms RichTextBox instead of a WPF RichTextBox?
+* [GitHub Sponsors](https://github.com/sponsors/vonhoff)
+* [Ko-fi](https://ko-fi.com/vonhoff)
 
-This sink is specifically designed for WinForms applications to avoid the WPF framework. Using a WPF-based logging component would require adding the entire WPF framework with all its dependencies, greatly increasing the size of the application.
+Every contribution of any size helps sustain ongoing development.
