What counts as a correction?

  • Factual errors in paper explanations (wrong year, wrong author, wrong claim)
  • Math errors in any section or tutorial
  • Code that doesn't run or gives wrong output
  • Broken links or missing references
  • Explanations that are confusing or misleading for a beginner
  • Spelling or grammar errors in English or Hindi

Suggestions for new content or new papers are also welcome — just label them as "suggestion" rather than "correction" in the issue.
