+## Ejemplo
+
+```go
+// Dado un script con:
+// #!/bin/bash
+// # Analisis completo de DNS para un dominio
+desc := shell.ExtractScriptDescription("/path/to/analisis_dns.sh")
+// desc == "Analisis completo de DNS para un dominio"
+
+// Sin comentario util
+desc2 := shell.ExtractScriptDescription("/path/to/instalar_go.sh")
+// desc2 == "instalar go" (fallback del nombre)
+```
+
+## Notas
+
+Busca en las primeras 5 lineas. Remueve prefijos comunes como "Script:", "Descripción:", "Description:" del comentario. Si el archivo no existe o no tiene comentarios utiles, genera una descripcion a partir del nombre del archivo reemplazando underscores por espacios.
