-## 9. Conclusion
+## 8. Conclusion
 
 The Codebase Context Specification provides a flexible, standardized approach to enriching codebases with contextual information for AI models. By adopting this convention and including role-specific information, development teams can enhance AI-assisted workflows, improving code quality and development efficiency across projects of any scale or complexity. The addition of role-specific guidelines and consistent naming conventions ensures that AI models have access to comprehensive, relevant, and well-structured information tailored to different aspects of the software development lifecycle.

 ## Codebase Context: A New Convention
 
 The Codebase Context Specification introduces a convention similar to `.env` and `.editorconfig` systems, but focused on documenting your code for both AI and humans. Just as `.env` files manage environment variables and `.editorconfig` ensures consistent coding styles, CCS files (`.context.md`, `.context.yaml`, `.context.json`) provide a standardized way to capture and communicate the context of your codebase.

+## 📁 .contextignore Files
+
+`.contextignore` files allow you to specify patterns for files and directories that should be ignored by the Codebase Context Lint. This is useful for excluding generated files, dependencies, or any other content that doesn't need context documentation.
+
+### How to use .contextignore
+
+1. Create a file named `.contextignore` in any directory of your project.
+2. Add patterns to the file, one per line. These patterns follow the same rules as `.gitignore` files.
+3. The linter will respect these ignore patterns when processing files in that directory and its subdirectories.
+
+Example `.contextignore` file:
+
+```
+# Ignore node_modules directory
+node_modules/
+
+# Ignore all .log files
+*.log
+
+# Ignore a specific file
+path/to/specific/file.js
+
+# Ignore all files in a specific directory
+path/to/ignore/*
+```
+
+The linter will validate the syntax of your `.contextignore` files and warn about any problematic patterns, such as attempting to ignore critical context files.
+
