Good reasons to get in touch

  • A Lean snippet no longer compiles.
  • A tactic explanation is unclear or missing an important edge case.
  • You found a typo, broken link, or outdated installation step.
  • You want to suggest a new tutorial topic.

Corrections

Corrections are prioritized when they affect runnable code, installation steps, or the meaning of a proof. If a page is updated after a correction, the change is reflected in the article content and the sitemap on the next deployment.

Please do not send private credentials, account secrets, or unpublished research material. Lean examples should be small enough to paste into a single.lean file.
