2. ADMIN: Create a new field group for posts and add a field to that
3. ADMIN: Fill in content for posts including the ACF custom field and do this to create posts with each status: published, private, password-protected, draft, and trashed
4. CONTRIBUTOR: Add shortcode to any post and specify/guess any post ID (of any status) and ACF field meta key and save
5. CONTRIBUTOR: Preview the post and see the custom field value outputs
