Worked on the ks-no/ks-nohub.io.git repository to improve API documentation by removing outdated references and aligning the docs with current API capabilities. Focused on documentation hygiene, the developer eliminated deprecated fiksio/katalog/lookup mentions, reducing confusion for future integrators and minimizing the risk of integration errors. All updates were consolidated into a single, traceable commit, ensuring clarity and maintainability. This work, carried out using Markdown and leveraging skills in API integration and documentation, directly contributed to a smoother onboarding process for new developers and lowered ongoing support needs by ensuring that the documentation accurately reflected the state of the API.
