.debug

This assumes you have your SVN in another server.

• Install PHP on your IIS using the web installer at http://php.iis.net/.  Don’t do anything else. Yes, I know there are some articles out there where you need to tinker with some settings using FastCGI or some crap like that.  IGNORE THOSE.
• Grab the latest WebSVN zip and uncompress the files in %windir%\inetpub\iisroot\websvn
• Download and install SlikSVN for the SVN binaries
• Add your local admin to have full control on %windir%\inetpub\iisroot\websvn
• Set local users to have full control on %windir%\inetpub\iisroot\websvn\cache (because it’s not full control by default).  this folder is used by WebSVN to cache the RSS feeds it creates.
• copy %windir%\inetpub\iisroot\websvn\includes\distconfig.php to config.php.  Edit with your favorite text editor and change the following lines:

$config->setSVNCommandPath('C:\\Program Files\\SlikSvn\\bin');
$config->addRepository('LOLCats Rule', 'svn://path_to_your_repository/', 
  NULL, 'your_svn_repo_username', 'your password');

And that’s it.  when you go to http://your-server-name/websvn/ you should see your brand spankin’ new SVN repository.
