+**Global vs. project scope.** `one init` is interactive and asks where the setup should live:
+
+- **Global** (`~/.one/config.json`) — applies to every folder. Best when you only need one workspace / API key.
+- **Project** (`~/.one/projects/<slug>/config.json`) — scoped to the current project, stored under your home directory so secrets never land in git. Use this when different projects need different API keys, connections, or access control.

+When you run `one` in a project, it uses the project config if one exists and falls back to the global config otherwise. Use `one config path` to see which config is active and the full resolution order.

+# Project vs. global config
+
+The One CLI can be configured at two scopes:
+
+- **Global** — `~/.one/config.json`. Applies everywhere the user runs `one`.
+- **Project** — `~/.one/projects/<slug>/config.json`, where `<slug>` is the project root path with slashes replaced by dashes (e.g. `/Users/jane/acme` → `-Users-jane-acme`). Only applies when running `one` from inside that project folder.
+
+**Resolution order:** env vars → `.onerc` in cwd → project config → global config. Project config wins when present; otherwise the CLI falls back to the global config.
+
+## When to suggest project scope
+
+Suggest project scope when the user wants any of the following for a specific folder only, without changing their default setup:
+
+- A different One API key (e.g. sandbox workspace for a client project)
+- A different set of connections / connection keys
+- Different access control (permissions, scoped connections, knowledge-only mode)
+
+## How to set it up
+
+Do **not** hand-edit `.onerc` or config files. Walk the user through the interactive init:
+
+```bash
+cd /path/to/the/project
+one init
+```
+
+When `init` asks "Where should this setup live?", pick **"This project only"**. Init will write the config to `~/.one/projects/<slug>/config.json` and everything else (skill install, MCP) stays untouched.
+
+To see which config is currently active and the full fallback chain:
+
+```bash
+one --agent config path
+```
+
+To switch an existing project back to using the global config, delete its project config file — the CLI will automatically fall back to global on the next run.
