+## Natural-language flow runner (`flow.ts`)
+
+Use `flow.ts` when you want a general command style like:
+
+- "go to this site"
+- "find this button and click it"
+- "type this and press enter"
+
+### Example
+
+```bash
+npx tsx flow.ts --instruction 'go to https://example.com then click on "Sign in" then type "stef@example.com" in #email then press enter'
+```
+
+You can also use JSON steps for deterministic runs:
+
+```bash
+npx tsx flow.ts --steps '[{"action":"goto","url":"https://example.com"},{"action":"click","text":"Sign in"}]'
 ```
