Worked on the incubateur-ademe/nosgestesclimat-site-nextjs repository to improve onboarding and setup reliability by enhancing installation documentation. Focused on clarifying prerequisites and launch instructions, the work aimed to streamline the local development environment for new contributors and reduce setup friction. The technical approach involved updating Markdown files to provide clearer, more maintainable guidance aligned with project standards. Collaboration with other contributors ensured that documentation changes addressed cross-team needs and improved overall developer experience. The effort centered on documentation and project setup, resulting in a single feature delivered through two commits, with no bug fixes during the one-month contribution period.
