## Getting Started

There are a few concepts the user must be familiar with in order to fully understand this user's guide, so before proceeding any further we'd like to clarify the terms.

Key concepts

A prototype is a representation of a software program that includes only a few aspects of the eventual application and resembles it up to some degree and whose purpose is to illustrate how that application is to look and behave to get an impression of its capabilities and shortcomings. It may also be referred to as mock-up or wireframe.

The user interface is the collection of all the visual components that make up an application's screen and that have a graphical representation on it. It also comprises meta data on these elements such as their layout disposition or their behaviour patterns under certain events.

A screen is a group of visual components gathered into a canvas or editing area. It may also be referred to as page and is browsed at once.

A functional scenario is a graph of application components that represent the application's general behaviour such as its navigability or its processing.

A comment is a user's written remark often related to an added piece of information on an element of a prototype. It may also be referred to as annotation.

Starting the application

To start the Justinmind Prototyper® you just need to go to the installation folder (or any shortcut you may have chosen to create in the operating system menu/desktop) and double click on the icon. After that, a start-up image with a loading progress bar displays for a short time, right before the actual application interface comes up. If it is the first time you start the application or if you have not disabled the functionality in the File > Preferences menu, a welcome window which displays shortcuts for the most common tasks prompts. This window offers a handful of options to quickly start off with the program.
