Giving WordPress its Own Directory – woe is me – help!

Hi all,

I’m trying to meticulously follow the instructions in this post but I’m running into trouble, confusion and error messages:

http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory

Step 9 baffles me as it asks me to change a line that is NOT in my index.php file:

require(‘./wp-blog-header.php’);

All the index.php files I have as reference from other templates only have this line:

<?php get_header(); ?>

Also… I initially installed WP in its own directory and thus don’t need to do it now, and much of these instructions seems to be about doing that. I’m wondering if that might be messing me up too.

This whole process is the ideal way to have a “customizable” home page at my root URL, right? The other stuff, categories, posts, etc, can live in my (existing) /wordpress subdirectory, that’s fine by me, but I want a home page with my most recent blog entry plus summaries of a couple of other categories.

Thanks!
Adam
