Worked on the pi-hole/docs repository to enhance documentation related to environment variable configuration. Focused on clarifying that environment variables can be set using either the exact configuration name or the conventional ALL_CAPS format, the update included a practical Markdown example demonstrating their functional equivalence. This documentation improvement aimed to reduce user confusion, streamline onboarding, and minimize configuration errors by aligning instructions with established naming conventions. The work leveraged skills in technical writing and documentation best practices, emphasizing clarity and maintainability. No bugs were addressed during this period, and the primary contribution centered on improving the accuracy and usability of project documentation.
