How to reach the people who curate these notes.

Write to hello@klayout.com.

That inbox is monitored by the site curators. There is no phone line and no ticket system — email is the right channel.

What to write about

  • Corrections — a wrong rule, a mixed-up process, a figure that misleads. Include the page URL and what you expected instead.
  • Tutorial stuck points — a step in the chip tutorial series that does not reproduce on your machine (tool version and error text help).
  • Privacy or AdSense — questions about cookies, the privacy policy, or advertising on this site.
  • Permissions — quoting a short passage with attribution is fine for education; ask before republishing a full note or figure set.

What this inbox is not

It is not customer support for any layout editor, foundry, or board house. It is not a design-review service for private tapeouts. Product manuals and PDKs remain the authority for manufacturing decisions — see the disclaimer.
