Read 2026-11-05. Source: https://agentreadyhtml.com/vendors/readme/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # ReadMe: vendor profile In short ReadMe builds llms.txt and .md copies, but an admin has to switch on Markdown for Agents before Accept: text/markdown returns markdown. docs.readme.com answered a missing page with a 404 and a 430-byte markdown body. New projects get an MCP server by default. Starter is free, and Pro is $250 a month. ## At a glance **standards.txt** readme ```text llms-txt = supports markdown-negotiation = partial markdown-twin = supports initial-html = no statement real-404 = supports vary-accept = no statement ``` 3 supports, 1 partial or announced, 2 no statement. **ReadMe** Docs platform ReadMe is a hosted API docs hub that builds llms.txt from the sidebar, serves .md copies of pages, sends markdown on Accept: text/markdown once Markdown for Agents is switched on, and gives paid plans custom 404 pages and redirects.

its redirect list only catches paths that would otherwise 404. ## Related pages on this site - [Docs platforms in this section](https://agentreadyhtml.com/vendors/by-type/docs-platform/) - [ReadMe: platform profile and rubric scores](https://agentreadyhtml.com/platforms/readme/) - [The Plain Fetch viewer](https://agentreadyhtml.com/viewer/) ## Sources 1.
