Worked on the iqm-finland/iqm-client repository to enhance documentation reliability and maintainability. Focused on improving Sphinx documentation workflows by configuring the build process to treat warnings as errors, ensuring that any documentation issues are caught early in CI/CD pipelines. Addressed and resolved existing Sphinx warnings, which improved the overall quality and consistency of the documentation. Updated the changelog to reflect the release of version 21.0 and documented fixes related to earlier versions, providing clear communication to users. Utilized Python, reStructuredText, and CI/CD tools to streamline documentation processes and maintain accurate, up-to-date project information for end users.
