If you were like me and found siteAuthor in config.php and assumed Jigsaw only supported one author, then, my friend, you've come to the right place. The process of adding more than one author isn't too difficult you just have to know it's possible and where to make the necessary tweaks.

When you first install Jigsaw you'll have a config.php that starts with a section that looks like this:

config.php

    'baseUrl' => '',
    'production' => false,
    'siteName' => 'Blog Starter Template',
    'siteDescription' => 'Generate an elegant blog with Jigsaw',
    'siteAuthor' => 'Author Name',

    // collections
    'collections' => [
        'posts' => [
            'author' => 'Author Name', // Default author, if not provided in a post
            'sort' => '-date',
            'path' => 'blog/{filename}',
        ],
        'categories' => [
            'path' => '/blog/categories/{filename}',
            'posts' => function ($page, $allPosts) {
                return $allPosts->filter(function ($post) use ($page) {
                    return $post->categories ? in_array($page->getFilename(), $post->categories, true) : false;
                });
            },
        ],
    ],

Now siteAuthor struck me as sounding like a pretty big deal and I, incorrectly, assumed it was meant to imply the site could only be authored by one person. Further down there is a collections->posts->author which I figured set the author on all of the posts since I didn't see an author in example posts.

It turns out that siteAuthor is only used in source/_layouts/rss.blade.php out of the box. That may have change in your Jigsaw blog so it'd be worth searching the source directory for siteAuthor. In rss.blade.php siteAuthor sets the author of the blog. This means if you didn't want there to be only one author you can set it to something more general like Engineering Blog or Cosmetology Blog. Then either all of your engineer friends or cosmetology friends could blog there.

The collections->posts->author in config.php is the author that's used when no author is specified on a post. That begs the question: How do you specify an author on a post? It's pretty straightforward. When you make a post add an author attribute to the meta information at the top like so:

meta information with author at the top of a post:

Now that I know how to do it I feel a bit silly. It's a feeling I get quite often after I learn something new. What surprising simply but useful thing have you learned recently? Let me know by dropping me a line on the contact page.
