0ne Ai
The practical user guide. Every concept and every skill in 0ne, explained page by page in plain English. Foundations cover what 0ne is, the folder tree, CLAUDE.md, memory, skills, hooks, the way One actually thinks. Skills cover every command you can run: research, content, daily work, building. Open a page, read three sections, know what to type. Read in order if you're new, skim by skill once you're not.
