<h4>How It Works</h4>

<li>Install and activate the plugin</li>
<li>Go to Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Saiy2k Nostr Components to configure</li>
<li>Enable only the components you need</li>
<li>Add blocks in the Gutenberg editor or use shortcodes</li>
<li>Configure relays and theme settings as needed</li>
</ol>
<h4>Example Usage</h4>
<p><strong>Gutenberg Blocks:</strong><br />
Simply add the Nostr blocks from the block inserter and configure them in the block settings.</p>
<p><strong>Shortcodes:</strong><br />
    [nostr_zap pubkey=”npub1abc…” url=””]<br />
    [nostr_post eventid=”note1abc…”]<br />
    [nostr_profile pubkey=”npub1abc…”]<br />
    [nostr_profile_badge pubkey=”npub1abc…”]<br />
    [nostr_follow_button pubkey=”npub1abc…”]<br />
    [nostr_like]</p>
<h4>Adding Like and Zap Buttons to All Posts/Pages</h4>
<p>To automatically add Like and Zap buttons to the end of every post and page:</p>
<ol>
<li>Go to <strong>Appearance <span aria-hidden="true" class="wp-exclude-emoji">→</span> Theme Editor</strong> (or use a child theme for safer customization)</li>
<li>Select your active theme (or child theme)</li>
<li>Open <code>functions.php</code></li>
<li>Add the following code at the end of the file:</li>
</ol>
<p>[code]<br />
// Add shortcode to the end of every post and page<br />
function add_shortcode_to_content($content) {<br />
    // Only add in single posts and pages (not homepage or archives)<br />
    if (is_singular([‘post’, ‘page’]) && in_the_loop() && is_main_query()) {<br />
        $shortcode_1 = do_shortcode(‘[nostr_like]’);<br />
        $current_url = esc_url(get_permalink());<br />
        $shortcode_2 = do_shortcode(‘[nostr_zap npub=”[YOUR-NPUB-GOES-HERE]” url=”‘ . $current_url . ‘”]’);</p>
<pre><code>    $content .= '<div class="nostr-shortcode-wrapper">' . $shortcode_1 . '<br/><br/>' . $shortcode_2 . '</div>';
}
return $content;
</code></pre>
<p>}<br />
add_filter(‘the_content’, ‘add_shortcode_to_content’);<br />
[/code]</p>
<p><strong>Important Notes:</strong><br />
* Replace <code>[YOUR-NPUB-GOES-HERE]</code> with your actual Nostr public key (npub format)<br />
* Always use a child theme when modifying theme files to preserve changes during theme updates<br />
* The buttons will only appear on single post and page views, not on archive pages or the homepage</p>
