<h3>Getting Started</h3>
<ol>
<li>
<p>On activation, the plugin will prompt you to index your content. You need to do this first before you will be able to see the various blocks used on your site. You can also go to <em>WP-Admin > Tools > Block Catalog</em> to do this yourself. Alternately, you can run the WP CLI command <code>wp block-catalog index</code> to index your content from the command line.</p>
</li>
<li>
<p>Once indexed, you will be able to see the different blocks used on your site in the Block Catalog Taxonomy.</p>
</li>
<li>
<p>Navigating to any Block Editor post type will also show you the list of blocks present in a post.</p>
</li>
<li>
<p>You can also filter the listing to only show Posts that have a specific block.</p>
</li>
</ol>
