\section{First use}
\subsection{Launching ViTE}
After getting \ViTE (by compiling or executables), you can go to the vite directory. The executable is in \verb?bin/vite? if you have just compiled from the source directory with configure or \verb?src/vite? with \textit{cmake}.
When you launch \ViTE without any options (these will be described in the section \ref{shortcuts}), you will have a window like the one in the figure \ref{launching}~:
\begin{figure}[hbtp]

\includegraphics[width=12cm]{images/launching}
\caption{\label{launching}{Launching of Vite}}
\end{figure}
\subsection{Open a file}
Go to the \verb?File? menu and click on \verb?Open?. A dialog box will appear and you will have to choose the file you want to open.
After choosing it, you must click on \verb?Open? to open the file or \verb?Cancel? if you do not want to open the selected file.
The other option to open a trace is to use drag and drop. Select your trace in a file manager and drop it on the \ViTE window.
Moreover, a recent file list has been done in order to easily open the recent traces. It keeps in memory the last ten traces opened.
You can also reload the current trace. This is useful when you visualize a trace, do some modifications on the file and do not want to launch \ViTE again.
If you try to open a file which is not recognised by \ViTE, error messages will be displayed.
\subsection{Navigation under the trace}
You can change the position and the scale by moving the horizontal and vertical scroll bars.
You can also zoom in or out by clicking in the zoom button.
You can select an area with the mouse to zoom in. You can also directly set a zoom level by selecting a zoom level in the bottom right. It is also possible to select an area to zoom by clicking, and keeping the clic while moving, the zoom will be in the rectangle defined by the beginning and the end of the clic. The use of the right clic undo the previous zoom.
You can go to the beginning or the end of the trace by clicking on the left and rigth arrow button and view the whole trace by clicking on the \verb?Show all? button.
You can see the trace in fullscreen going on the \verb?View? menu and picking \verb?fullscreen?.
Moreover, it is possible to hide the links and/or the events using the \textit{No arrow} and \textit{No Event} buttons of the toolbar.
An other option is to get informations about an event, a state, a communication in the trace by clicking over this element on the screen. If a lot of elements are grouped, you may be forced to zoom to be able to get the right information about the element.
