<p>Since we provide YaCy as a generic release for all operation systems and a special 'flavour' for Windows users, we distinguish two different processes for installation. Windows users may want to <ahref="#wininst">switch to the Windows installation instructions</a>, however, the following description is more general and applies to all operation systems:
<p>Installation of YaCy is VERY EASY! Just follow the <b>simple three steps</b> for either <ahref="#linuxinst">Linux</a>, <ahref="#macinst">Macintosh</a> or <ahref="#wininst">Windows</a> operating systems. If you upgrade from a previous version of YaCy, please see the <ahref="#upgradeinst">Upgrade Instructions</a>.
the latest release, simply decompress the archive with your favourite tool
(which can be WinRar or WinZip on Windows, or Stuffit Expander on Mac OS X; Linux
users type 'gunzip <release>.tar.gz' and 'tar -xf <release>.tar') and move the result to any place you want.</p>
<p>If you upgrade from a previous version of YACY, <b>please migrate your settings and data</b>.
This is very easy: simply move (not copy) your DATA directory from the application root directory of the old YACY installation to the new application root directory. If done so, you don't need to do the other remaining configuration steps below again.</p>
<p>Change the proxy settings either in your network configuration or directly in you browser. Check the 'Use HTTP Proxy' flag and configure the IP and port according to the location of the proxy. If you do a single-user installation without changing the configuration in #2, the IP/Host shall be set to '127.0.0.1' or 'localhost', and the Port shall be set to '8080'.</p>
