Customer Site Settings – llms.txt

Overview

As of Release 2026.05 (4.16.0) the llms.txt customer site setting allows you to define content for a llms.txt file served on your site’s domain.

Important Notes

• The llms.txt file is only accessible on customer domains. It is not served on shared platform domains (e.g., cimproduction.com, cimstaging.com, mycimcloud.com) to prevent accidental crawling.
• Content is configured individually per customer site, allowing each site to provide its own tailored information to AI tools.
• The content should follow the llms.txt markdown format — starting with an H1 title, an optional blockquote summary, and organized sections with links to key resources.
