+**Clipboard (default)** — `ostt -c` copies the transcript with `wl-copy`
+(Wayland) or `xclip` (X11). Paste it anywhere with your normal paste; the
+transcript is also readable from scripts via `wl-paste`.
+
+**Paste (opt-in)** — `ostt --paste` copies the transcript, then injects a
+single paste shortcut (`wtype`/`ydotool`/`xdotool`) into the focused app. Per
+the [OSTT docs](https://ostt.ai/guide/configuration#paste-output) it sends
+exactly one configurable key — default `ctrl+v` — and cannot detect success,
+so it silently does nothing in apps with a different paste binding (terminals
+usually want `ctrl+shift+v`). Tune `[output.paste] paste_key` in
+`~/.config/ostt/ostt.toml` before enabling it.
