Install
# Install Cursor rule to .cursor/rules/ mkdir -p .cursor/rules && curl --retry 3 --retry-delay 2 --retry-all-errors -o .cursor/rules/langchain-docs.mdc "https://raw.githubusercontent.com/leonyangdev/lc-studylab/main/.cursor/rules/langchain-docs.mdc"
Run in your IDE terminal (bash). On Windows, use Git Bash, WSL, or your IDE's built-in terminal. If curl fails with an SSL error, your network may block raw.githubusercontent.com — try using a VPN or download the files directly from the source repo.
