# Getting Started

There are two types of simulation can be carried out, which are: Reaction and Prediction in order to simulate the environment. The user will be able to get to the simulation menu by clicking the "Simulation" on the control panel, which is located in the left of the window.

Once in the simulation mode, there are two choices to choose from, which are: Reaction and Simulation. Image of simulator window

### Reaction

The reaction setting is the more simple of the two settings to use, as it requires far less configuration than the prediction setting. It is mainly inteded to be used as a quick simulation to be able to check the flow of customers in and out of the tills and each individual customer's happiness levels.

### Prediction

The prediction setting is quite different to the reaction setting, instead of running a simulation in realtime by putting in a set number of customers, you are able to change all of the settings related to the store. This allows for improved accuracy in monitoring the average happiness throughout the store, as well as the average number of items bought by the customers.
