                                    <p>Thanks for taking the time to download and install cacti, the complete graphing
                                    solution for your network. Before you can start making cool graphs, there are a few
                                    pieces of data that cacti needs to know.</p>

                                    <p>Make sure you have read and followed the required steps needed to install cacti
                                    before continuing. Install information can be found for
                                    <a href="../docs/html/install_unix.html">Unix</a> and <a href="../docs/html/install_windows.html">Win32</a>-based operating systems.</p>

                                    <p>Also, if this is an upgrade, be sure to reading the <a href="../docs/html/upgrade.html">Upgrade</a> information file.</p>
