[Theme: Hatch] Portfolio page displaying several categories

Hello there! First of all, I’ve got to say that my WordPress skills are not really good but I’m trying to learn 🙂

Well, the thing is that I’m trying to run this website: http://www.saravilassantiago.com based on Hatch theme, which, if needed is built with Hybrid framework.

It works like charm except for the “Portfolio” part. Here’s is the thing: I’m graphic designer, so I have works in really different areas (each one will be set in a different category) but I can not display multiple categories in one page. In fact, I can not even display one properly.

There’s not a “category.php” file or similar for the Category template. It’s something about hierarchy because I found this in a file named “template-hierarchy.php”:

function hybrid_taxonomy_template( $template ) {
	/* Get the queried term object. */
	$term = get_queried_object();
	/* Remove 'post-format' from the slug. */
	$slug = ( ( 'post_format' == $term->taxonomy ) ? str_replace( 'post-format-', '', $term->slug ) : $term->slug );
	/* Return the available templates. */
	return locate_template( array( "taxonomy-{$term->taxonomy}-{$slug}.php", "taxonomy-{$term->taxonomy}.php", 'taxonomy.php', 'archive.php' ) );
}

But I can’t find anywhere the taxonomy.php file neither.

So, I was trying to copy and paste the code from the original home.php, where you got posts displayed (you can see the Hatch original demo here: http://devpress.com/demo/hatch/). Then, I added to the top the query_posts line to display just the category I want, so I had this:

<?php do_atomic( 'before_content' ); // hatch_before_content ?>
       <?php query_posts('cat=3'); ?>
	<div id="content">
		<?php do_atomic( 'open_content' ); // hatch_open_content ?>
		<div class="hfeed">
			<?php if ( have_posts() ) : ?>

Plus header, the rest of the copied code from home.php and footer.

For some reason, this shows up like this: http://saravilassantiago.com/portfolio/ instead of showing up like this: http://saravilassantiago.com/category/web/

I tried changing the line of query_posts, but it doesn’t want to work!

Any suggestion about this issue?

Also, any suggestions (when this part is solved) about how to add multiple categories? (Should be something simple like <h1>BRANDIND</h1> *here branding category posts* and so on with the rest of categories I need to add)

Thank you so much in advance! I’ve been reading and messing the code around for days! :/
