During November 2025, Zeid Abadi contributed to the marmelab/react-admin repository by updating its documentation to reflect the adoption of React 18’s createRoot API. Zeid replaced the deprecated ReactDOM.render method in the README, ensuring that onboarding materials and code examples align with current React best practices. This work, implemented using JavaScript and Markdown, focused on front end development and improved the clarity of guidance for both new and existing contributors. By synchronizing documentation with the actual implementation, Zeid helped reduce confusion and potential support requests, though the scope of work was limited to documentation rather than feature development or bug fixes.
