<p>Add the <strong>Table of Contents Block</strong> anywhere in your Gutenberg editor. It scans H2–H6 headings in the post content and builds a nested, clickable table of contents. Links automatically work by adding IDs to headings.</p>

<li>No theme editing required<br />
You can activate the plugin on any site.</li>

– Structure Your Content – Write your post or page using semantic headings (H2, H3, etc.)—just like you normally would.<br />
– Insert the Table of Contents Block – Add the “Table of Contents Block” anywhere in your editor (e.g., right after the introduction).<br />
