-Kitchen Ticket for Odoo Point of Sale
-=====================================
-
-This module allows to print a kitchen ticket, which is the same ticket than normal
-but without prices and taxes. This will be useful when the order is done internally
-without the payment.
-
-It has a additional **Payment** button on the Kitchen Ticket window to change the
-flow from **Payment->Receipt** to **Receipt->Payment**.
-
-This module target the POSBoxless environments, as the POSBox environment already 
-have a Bill printing method which can be enabled with pos_restaurant module that 
-Odoo provides.
-
-Usage
-=====
-
-Just press the *Kitchen Ticket* button that appears below the order
-
-
-Installation
-============
-
-Nothing special is needed to install this module.
-
-
-Configuration
-=============
-
-No configuration needed.
-
-
-Known issues / Roadmap
-======================
-
-Missing features
-----------------
-* Not tested with a **PosBox setting** so surely will not work if *'print by
-proxy'* is enabled.
