== Installation ==

1. Upload the `endmark` folder to `/wp-content/plugins/`
2. Activate the plugin through 'Plugins' menu
3. Go to Settings → Endmark to configure

== Frequently Asked Questions ==

= Can I use an image instead of a symbol? =

Yes! Select "Image" as the endmark type, then click "Upload Image" to select from your Media Library.

= Where does the endmark appear? =

By default, at the end of the last paragraph. If using footnotes, it appears just before them. You can change this behavior in the Placement Mode settings.

= Can I manually place the endmark? =

Yes! Use the `[endmark]` shortcode or the Endmark Gutenberg block. When manually placed, automatic insertion is disabled for that post.

= Can I exclude certain posts or categories? =

Yes! In the Advanced Options, you can exclude specific categories, tags, or post IDs. You can also set a minimum word count.

= Does it work with footnote plugins? =

Yes! Endmark automatically detects footnotes from popular plugins and places the endmark before them (configurable).

= How do I customize the styling? =

If "Use CSS variables" is enabled, you can override the margins in your theme CSS:
`
:root {
    --endmark-margin-top: 0;
    --endmark-margin-left: 0.5em;
}
`
