 # AlguaBeep
 
-Une expérimentation hasardeuse pour traduire des images de webcam
+C'est une expérimentation hasardeuse pour traduire des images de webcam
-en sons qui déchirent les oreilles, mais qui sont bio-dégradables.
+en sons qui déchirent les oreilles, mais qui sont relativement
+inoffensifs. 
+
+Pour le moment, il n'y a pas de procédure d'installation, il faut
+donc lancer le binaire à partir du répertoire de dèv :
+`~/Devel/DD2-monitor/Beep/alguabeep [options]`, ce qui implique
+de ne pas aller mettre la grouille dans ce coin-là.
+
+Ensuite, pour apprécier pleinement la kitchitude (assumée) de l'affichage
+numérique de la machinerie en action, il faut un `xterm` en 150 caractères
+de large, et une toute petite fonte.
 
 ## Usage
 
 ```
+available options:
         -d /dev/?       select video device
         -I              take pictures
         -K              set the K parameter
