Enhance Documentation for Project Customization Examples

[loxneshow2003]

Issue

The documentation provides basic examples for project customization, but it could benefit from more detailed explanations and additional use cases.

Suggestion

1. Expand on the examples: Provide a more comprehensive explanation of each command used in the examples to ensure users understand their purpose and how to tailor them to specific projects.
2. Add use cases: Include various scenarios or project types where different filters and rules might be applicable. For instance, examples based on different programming languages or project workflows could be helpful.
3. Visual aids: Consider adding diagrams or flowcharts that illustrate how rules interact with each other and how they affect file selection and context generation.

By making these improvements, new users will find it easier to understand how to leverage the customization features effectively.

@loxneshow2003 please feel free to provide specific improvements in a PR. It would be best if the examples were based on an actual working repo rather than synthesized from scratch.
