WordPress.org

1. Upload the entire wp-timeline-archive folder to your wp-content/plugins/ directory.

2. Activate the plugin through the 'Plugins' menu in WordPress.

3. Create a post or page and include the short code: [tla]

   You can exclude categories using: [tla eid="23"] (where '23' is the category ID)

If you want to customize the style, just copy the CSS file 'wp-timeline-archive.css' from the plugin folder to your active theme folder and edit it.
