<h2>Installing WordPress µ</h2>
<p><strong>Welcome to WordPress µ.</strong> I will help you install this software by asking you a few questions and asking that you change the permissions on a few directories so I can create configuration files and make a directory to store all your uploaded files.</p>
<p>If you have installed the single-blog version of WordPress before, please note that the WordPress µ installer is different and trying to create the configuration file wp-config.php youself may result in a broken site. It's much easier to use this installer to get the job done.</p>
<h3>What do I need?</h3>
<ul>
<li>Access to your server to change directory permissions. This can be done through ssh or ftp for example.</li>
<li>A valid email where your password and administrative emails will be sent.</li>
<li>An empty MySQL database.Tables are prefixed with <code>wp_</code> which may conflict with an existing WordPress install.</li>
<li> Wildcard dns records if you're going to use the virtual host functionality. Check the <a href='http://trac.mu.wordpress.org/browser/trunk/README.txt'>README</a> for further details.</li>
</ul>

<p>Congratulations! <br />Your <a href='http://<?php echo $domain . $base; ?>'>WordPress µ site</a> has been configured.</p>
<p>You can <a href='wp-login.php'>log in</a> using the username "admin" and password <?php echo $pass; ?></p>
<h3>Directory Permissions</h3>
<p>Please remember to reset the permissions on the following directories:
<ul>
<?php
reset( $dirs );
foreach( (array) $dirs as $dir ) {
echo "<li>$dir</li>";
}
?>
</ul>
</p>
<p>You can probably use the following command to fix the permissions but check with your host if it doubt:
<br /><code>chmod 755
<?php
reset( $dirs );
foreach( (array) $dirs as $dir ) {
echo "$dir ";
}
?></code>
</p>

<h1>No-www</h1>
<p>WordPress µ strips the string "www" from the URLs of sites using this software. It is still possible to visit your site using the "www" prefix with an address like <em><?php echo $_POST[ 'basedomain' ] ?></em> but any links will not have the "www" prefix. They will instead point at <?php echo $nowww ?>.</p>
<p>The preferred method of hosting blogs is without the "www" prefix as it's more compact and simple.</p>
<p>You can still use "<?php echo $_POST[ 'basedomain' ] ?>" and URLs like "www.blog1.<?php echo $nowww; ?>" to address your site and blogs after installation but internal links will use the <?php echo $nowww ?> format.</p>
<p><a href="http://no-www.org/">www. is depreciated</a> has a lot more information on why 'www.' isn't needed any more.</p>
