				<h2 class="photonic-section">What is Gutenberg?</h2>
				<p>
					WordPress 5.0 introduced a new editor codenamed Gutenberg. Gutenberg features a different style of
					creating content, which introduces a concept called a <code>block</code>.
				</p>

				<h2 class="photonic-section">How does it impact Photonic on your site?</h2>
				<p>
					If you have configured Photonic not to use the standard <code>gallery</code> shortcode, and instead have
					a custom shortcode via <em>Photonic &rarr; Settings &rarr; Generic Options &rarr; Generic Settings &rarr; Custom Shortcode</em>,
					you are fine!
				</p>
				<p>
					<strong>But if you are using the <code>gallery</code> shortcode for Photonic and you click on
						"Convert to Blocks" using Gutenberg, your post will be in trouble!</strong> <span class="warning">All your instances of the
								<code>gallery</code> shortcode will be replaced by the native WordPress Gallery Block.</span>
				</p>
				<p>
					To avoid this you can find and replace all instances of the <code>gallery</code> shortcode
					used for Photonic and replace them with a custom shortcode of your choosing.
				</p>
