How to create a price list

Hello everyone,
thanks for the answers!
I have installed the price list module, but I have a problem: how do I create a price list for a customer?
How can I associate a product’s personalized price with a specific customer?
What should I enter in the name field in prile list?
In the lines I will insert the products with the prices, but the customer where I indicate it?
how can I associate the list price to the customer ???
