 Create `main.ts`. A command is a `CommandModule`; you map commands to routes with `defineManifest`, then dispatch with `run`:
 
 ```typescript
-import type { CommandModule } from './types/command'
-import type { Config } from './types/config'
+import { command } from './core/command'
 import { defineManifest, run } from './core/runtime'
 
-const hello: CommandModule = {

     const name = ctx.positionals[0] ?? 'World'
     ctx.io.write(`Hello, ${name}!`)

 Directory-scanned manifest (larger CLI) — pass `import.meta` and let `run()` discover commands from `config.commandsDir`:
 
 ```typescript
 import { run } from 'cti'
-import type { Config } from 'cti'
 
-const config: Config = { name: 'my-cli', commandsDir: 'commands', version: '1.0.0' }
-void run(config, import.meta)
+void run({ name: 'my-cli', commandsDir: 'commands', version: '1.0.0' }, import.meta)
 ```
 
 (You can also call `discoverManifest(commandsDir)` yourself and assign the result to `config.manifest` — useful if you want to inspect or modify entries before dispatch. Either way, `Manifest` ends up on `config.manifest`.)
