 A user's personal instance lives in `~/UnforcedAGI/` (a separate private repo) and uses the tooling from this package.
 
-## Install (future)
+## Install
 
 ```bash
 bun install -g github:Unforced-Dev/unforced-agi
 ```
 
+## Usage
+
+```bash
+unforced-agi launch    # start (or attach to) your UnforcedAGI session in tmux
+unforced-agi help      # show help
+unforced-agi version   # show version
+```
+
+`launch` creates a tmux session named `unforcedagi` rooted at `~/UnforcedAGI`,
+runs `claude` inside it, and attaches your terminal. Detach any time with
+`Ctrl-b d` — the session keeps running in the background. Run `launch` again
+to reattach. Requires `tmux` and `claude` on your `PATH`, and `~/UnforcedAGI`
+to exist.
+
 ## Roadmap
 
 - [ ] `unforced-agi init` — scaffold a new `~/UnforcedAGI/` directory for a user

 A framework for running a single Claude Code session as your personal
 primary agent — coordinating work across projects via Agent Teams,
 subagents, and knowledge graph memory.
 
 Commands:
+  launch     Start (or attach to) your UnforcedAGI session in tmux
   version    Show version
   help       Show this help
 
-(More commands will be added as needed. Currently a placeholder scaffold.)
