Worked on improving the documentation for the PyPSA/pypsa-eur repository, focusing on enhancing clarity and reliability for users. Addressed a bug in the Sphinx documentation system by correcting the literalinclude directive within the configuration guide, ensuring the correct enable section is included in the generated docs. This involved adjusting the marker from 'enable:' to '#enable' and using the start-after parameter, which reduced confusion for new users and streamlined onboarding. The work primarily utilized reStructuredText (RST) and Sphinx, emphasizing documentation skills over feature development. No new features were released during this period, with efforts concentrated on documentation quality.
