Set a primary category for your posts… and then do stuff with it.

**Why would I want a primary category?**

Out of the box, WordPress allows you to assign multiple categories to a post. Unless
you’re enforcing a strict one-category-per-post-only rule for your website, this
can be a problem now for displaying the most important category for your respective
posts, as opposed to WordPress automatically selecting it for you.

Let’s say that your blog is about animals, and you publish an article titled “Why
Do Dogs Love Water and Cats Hate It?” with the categories: _Cats_, _Dogs_, and _Pets_
assigned to it.

By default, anywhere that WordPress might display a single category to represent
the post, it’s probably going to display _Cats_ by default, but since the post is
equally about both cats and dogs, maybe the more general _Pets_ category would be
more appropriate.

This plugin allows you to accomplish that, whether it’s for presentational, structural,
organizational, SEO, or all of the above purposes.

**In what ways can I utilize a primary category?**

    ```
    [primary-cat]
    ```

In any creative way that you can imagine, but here are some examples I thought of:

 * To present the main category that the post belongs to above its title (by adding`
   <?php echo do_shortcode( '[primary-cat]' ); ?>` in your theme code, child theme,
   or custom functions plugin), in some aesthetic way (which can be styled with 
   CSS `.primary-cat`). Lots of blog, news, and magazine sites have this feature.
 * To have the appropriate slug in your post URLs if you’re using the custom `/%
   category%/%postname%/` permalink structure under _Settings > Permalinks_.
 * To have breadcrumbs (by using the shortcode `[primary-bread]`) on your site for
   user-friendliness (which can be styled with CSS `#breadcrumbs`), and can in turn,
   also improve SEO.

## インストール

 * Install and activate the plugin
 * Create or edit a post
 * You’ll now be able to set a category as the primary category or add your own 
   custom text
 * Use the `[primary-cat]` shortcode on any page, post, or text widget or in your
   theme code, with `<?php echo do_shortcode( '[primary-cat]' ); ?>`

## FAQ

### It’s not working?

 * You can enter whatever text you like into the Primary Category field to represent
   your post, and it’s not even required to actually be a registered category. However,
   for certain features to work right, like overriding the category slug in URLs,
   it needs to also be an actual category.
 * You may need to flush the permalinks by going to _Settings > Permalinks_ and 
   clicking on “Save Changes.”
 * You may need to clear any caches and refresh your browser.
