 # Demo Recording
 
-## Option A: vhs (recommended)
+`vhs` no funciona con CLIs interactivos como Claude Code. Hay que grabar manualmente.
 
-```bash
-brew install charmbracelet/tap/vhs
-vhs demo/demo.tape
-```
-
-Generates `demo/demo.gif`. Edit `demo.tape` to customize.
-
-## Option B: asciinema
-
-```bash
-brew install asciinema
-asciinema rec demo/demo.cast
-# Run the commands manually, then ctrl+d to stop
-# Convert to GIF:
-npm install -g svg-term-cli
-svg-term --in demo/demo.cast --out demo/demo.svg --window
-```
-
-## Option C: Manual screen recording
