# Contribute a subject Submit a new concept to the directory: a subject name, optional parent, and your text, run through a research pass and routed to moderators. The directory is built by contributions like yours. Each submission is reviewed and must pass a lint gate before joining the tree. ## The process Sign in, provide a subject name and content (or upload a file), and submit. A research pass generates an initial summary and fact sheet. Moderators review the findings and approve or request changes. Approved subjects land in the directory and the concept tree.
