Once you have Pm Wiki up and running on your site (see PmWiki.Installation), you may want to begin customizing Pm Wiki for your particular needs. Most Pm Wiki customizations are performed in a file called local/config.php.

When you first install Pm Wiki, the local/config.php file will not exist and so you'll have to create one if you want to perform any local customizations. You can either create config.php from scratch following the instructions below, or you can copy the sample-config.php file (in the same directory as pmwiki.php) to local/config.php and use it as a starting point.

Here is a very simple config.php file:

  
<?php
  $WikiTitle = "MyNewWiki";
  $PageLogoUrl = "http://www.example.com/mylogo.gif";
?>

Note that config.php should always begin with <?php and end with ?>. Be sure there aren't any blank lines or spaces before the <?php or after the ?>, or else you'll get strange PHP error messages at the beginning of your wiki pages.

The config.php file above is setting the value of two PHP variables used by Pm Wiki. The $WikiTitle variable gives the name of your site as it will appear in a user's browser title bar. The $PageLogoUrl variable specifies the URL of the icon image that will appear by default in the upper-left corner of each wiki page. Pm Wiki lets you set these (and other) variables in config.php so that you can change the look and feel of Pm Wiki from its default, sometimes substantially so. You can look at PmWiki.Variables for a list of variables that Pm Wiki uses, and also at PmWiki:PmWikiUsers for examples of other sites that are using Pm Wiki in customized ways.

After you've set up an initial config.php file, you can then begin to look at other Local Customizations you may wish to make to your wiki site. You will also want to visit the PmWiki Cookbook which provides a lot of customizations you may wish to try.

Don't forget to join a PmWiki mailing list, where you can email other WikiAdministrators for help on customizing Pm Wiki and participate in discussions about Pm Wiki improvements. And, once you have your site operational, be sure to add it to PmWiki:PmWikiUsers so others will know about it!
