Worked on improving codebase hygiene in the duneanalytics/dune-docs repository by updating the .gitignore file to exclude IDE configuration files, specifically those related to JetBrains IDEs (.idea). This change reduced repository noise and minimized the risk of accidentally committing local development environment settings, supporting cleaner diffs and safer code reviews. The update facilitated easier onboarding for new contributors and improved overall maintainability. The work was managed using Git, with a focus on version control best practices. Although no bugs were fixed during this period, the contribution addressed an important aspect of collaborative development and repository management for the project.
