 ```bash
-# With Babashka (simple sync runtime)
 bb counter
-bb timer
-bb list
-bb spinner
-bb views
-bb http
+```
 
-# With Clojure (full async support)
+### Timer
+Countdown timer with pause/resume - demonstrates async commands.

+![Timer](assets/timer.gif)
+
+```bash
+bb timer
+```
+
+### List Selection
