+Recording a session automatically saves it in a **stash-like index**, similar to how git stash works.
+For example, the most recent session is accessible as:
+```sh
+  replay run replay@{0}
+```
 ### Replay a Session
 To run a recorded session of commands :
 ```sh
-replay run # runs the last recorded session by default
+replay run  # runs the last recorded session (replay@{0})
+```
+You can also run a specific saved session by index:
+```sh
+replay run replay@{2}
 ```
