+### State Saving
+
+When `persist_state` is set to `true` in the config, Anyrun will:
+- Save the input text to a state file (`$XDG_STATE_HOME/anyrun` or `$HOME/.local/state/anyrun`), when the window is closed
+- Restore this text when Anyrun is launched again
+- Clear the saved state when a match is selected or copied
+
+You can optionally set `state_ttl_secs` to automatically discard saved state after a certain time. For example:
+```ron
+// Enable state persistence with 2-minute TTL
+persist_state: true,
+state_ttl_secs: Some(120)
+```
+
+This is useful for preserving your input between sessions, especially for longer queries or calculations.
