+<b>Descrizione</b><br>
+Questa è un\'implementazione della briscola in cinque, così come è spiegata su
+<a target=\\"_blank\\" href=\\"http://it.wikipedia.org/wiki/Briscola#Gioco_a_5\\">Wikipedia</a>; in breve è la variante con l\'asta prima sulla carta e poi sui punti.<br><br>
+<b>Uso del sito</b><br>
+Potete sedervi a un tavolo o rimanere in piedi.<br>
+Se al vostro tavolo si raggiungono i 5 giocatori inizia automaticamente la partita.<br>
+<br>
+<b>Partita</b><br>
+All\'inizio vengono distribuite le carte e parte l\'asta; per partecipare all\'asta, quando sarà il vostro turno, potrete scegliere se andare avanti o passare cliccando sulle icone corrispondenti. Se si arriva ai punti, scrivete nella textbox il vostro rilancio e cliccate PUNTI.<br><br>
+Chi vince l\'asta dovrà decidere il seme della carta scelta e inizierà la mano.<br>
+Per giocare le carte dovrete trascinarle nel quadrato al centro del vostro schermo.<br><br>
+Il vostro turno è sempre segnalato da una cornice verde lampeggiante intorno quadrato al centro del vostro schermo.<br><br>
+Durante la partita, se vorrete ricaricare la pagina, usate l\'apposito bottone \\"reload\\" in basso a destra.<br>
