-Before using this module, you need to define pricelists and set them complex. In order to do that, might be necessary to install **Sale** App.
+Before using this module, you need to define pricelists with "Advanced price rules" in point of sale settings (Pricing section).
 
 After that, you need to create a Pricelist with a Splitting partner configured and a rule with type **Split Invoice**.
 On that rule you need to set the base pricelist used to compute the total price, the pricelist used to split and the amount payed by the splitting partner.
 
-For example, if we have a Product with a Pricelist A of 100 and a Pricelist B of 80, and we specify that we use Pricelist A and the splitting partner pays 90% of Pricelist B, the final amount payed by the Customer will be: 100 - 80*90% = 28.
+For example, if we have a Product with a Pricelist A of 100 and a Pricelist B of 80, and we specify the price computation "Based on" Pricelist A and "Split amount based on" Pricelist B with "Split percentage" of 90%, the final amount payed by the Customer will be: 100 - 80*90% = 28.
 
-All the pricelists must be included on the Point Of Sale Configuration in order to proceed properly with the calculation.
