Worked on the Open-Pix/openpix-developers repository to streamline the invoice integration documentation by removing an outdated image reference and its associated file. Focused on improving the clarity and usability of the integration guide, the changes aimed to reduce onboarding friction for new developers and minimize future maintenance for the documentation team. Utilized Markdown for precise documentation updates and demonstrated strong documentation hygiene through clear commit messaging and adherence to feature-driven workflows. The work ensured that the documentation accurately reflected the current invoice integration process, supporting a smoother onboarding experience and aligning the guide with the latest integration requirements and best practices.
