Worked on enhancing the developer experience for the neo4j-labs/llm-graph-builder repository by refining project documentation. Focused on clarifying the configuration process for LLM models, the work included updating the README to provide a dedicated Markdown code block that demonstrates how to specify OpenAI API keys. Addressed a typo and formatting issue in the environment variable example to prevent misconfiguration, ensuring the documentation accurately reflects current usage patterns. Linked documentation changes to relevant issues and commits for traceability. Leveraged skills in documentation and Markdown to streamline onboarding for future contributors and support consistent, accurate setup of LLM model integrations.
