+								<h2 class="font-bold">Sweep leaves left</h2>
+								<p>
+									If disabled, an expanded tile's children are simply laid out in order.
+									This can leave a lot of empty space when large children are next to small ones.
+									Moving the unexpanded children (the 'leaves') to the left helps avoid this.

+								<h2 class="font-bold">Trees to use</h2>
+								<p>
+									Three choices are available, and all are simplified versions of
+									the tree from the Open Tree of Life.
+									<span class="text-xs md:text-sm text-stone-500">
+										(Without this, some nodes would have over 10,000 children, and
+										significantly slow the browser down during rendering)
+									</span>
+								</p>
+								<ul class="list-[circle] pl-4">
+									<li>
+										<span class="font-bold">Complex:</span>
+										The least simplified choice. In short, it only includes
+										nodes that have an image or description, with a soft limit of 600 children.
+										<span class="text-xs md:text-sm text-stone-500">
+											(Has about 450,000 nodes)
+										</span>
+									</li>
+									<li>
+										<span class="font-bold">Visual:</span>
+										Only keeps nodes with images, with a soft limit of 300 children.
+										<span class="text-xs md:text-sm text-stone-500">
+											(Has about 140,000 nodes)
+										</span>
+									</li>
+									<li>
+										<span class="font-bold">Minimal:</span>
+										Created using a rough list of 'well known'
+										taxons, and adding a few more at random.
+										<span class="text-xs md:text-sm text-stone-500">
+											(Has about 3,300 nodes)
+										</span>
+									</li>
+								</ul>
+							</li>
+							<li>
+								<h2 class="font-bold">Slider Resets</h2>
+								<p>
+									You can {{touchDevice ? 'tap' : 'click'}} on
+									a slider's label to reset it to the default value.
+								</p>
+							</li>

+						<br/>
+						<h1 class="text-lg font-bold">Keyboard Shortcuts</h1>
+						<ul class="list-disc pl-4">
+							<li>Ctrl-F opens the search bar</li>
+							<li>Ctrl-Shift-F toggles the search animation</li>
+							<li>Esc closes an open pane, and cancels an active search or auto mode</li>
+						</ul>
+						<br/>
+						<h1 class="text-lg font-bold">Unusual Node Names</h1>
+						<ul class="list-disc pl-4">
+							<li>
+								<h2 class="font-bold">Disambiguation Nodes</h2>
+								<p>
+									These have names like 'Iris [2]'. When multiple nodes have the same
+									name, all but one gets an '[N]' appended, where N is 2 or above.
+								</p>
+							</li>
+							<li>
+								<h2 class="font-bold">Compound Nodes</h2>
+								<p>
+									These are only present in the Complex tree, and have names like
+									'[Homo Sapiens + Homo Heidelbergensis]'. They provide structure for other nodes,
+									and are named after two prominent descendants.
+								</p>
+							</li>
+						</ul>
+						<br/>
+						<h1 class="text-lg font-bold">Overflowing Tiles</h1>
+						<p>
+							Some tiles have too many children to fit on-screen at once, and are displayed
+							with a scroll bar. For layout reasons, this is only done if they are the
+							outermost tile, so you may need to {{touchDevice ? 'double tap' : 'click and hold'}}
+							the tile to expand it.

+								 version 13.4, accessed 23/04/2022.

+							<li>
+								The images and alternative-names data was partly obtained from the

+									>here</a><external-link-icon :class="linkIconClasses"/>,

+								accessed 24/04/2022.
+							</li>
+							<li>
+								The short descriptions, along with the remaining images and name data,
+								were obtained from Wikipedia. Descriptions were extracted from the
+								<a href="https://dumps.wikimedia.org/enwiki/" :style="anchorStyles">Wikipedia dump</a>
+									<external-link-icon :class="linkIconClasses"/> for 01/05/22,

+						<br/>
+						<h1 class="text-lg font-bold">Data Inconsistencies</h1>
+						<p>
+							When handling datasets this large, these are almost unavoidable. Significant effort
+							was expended to minimise them, but, inevitably, there are always more. The most prominent
+							types are listed below. If you find a major error, feel free to let me know at
+							<a href="mailto:terry06890@gmail.com" :style="anchorStyles">terry06890@gmail.com</a>.
+						</p>
+						<ul class="list-disc pl-4">
+							<li>
+								<h2 class="font-bold">Errors in Node Linkage</h2>
+								<p>
+									The datasets don't share the same set of node identifiers. So, in order to
+									link nodes from one dataset with another, their plain names were used.
+									This doesn't work when names are ambiguous. For example, 'Proboscidea'
+									might denote a taxon for elephants, but also plants. Most of these were
+									manually corrected, but there are almost certainly more.
+								</p>
+							</li>
+							<li>
+								<h2 class="font-bold">Errors Within the Datasets</h2>
+								<p>
+									Some issues are internal to the datasets themselves. For example, an image from
+									EOL might display a plant that is in the wrong taxon. As most of the datasets are
+									large projects distributed over many people over a long period of time, these
+									errors are difficult to avoid, and may require specialised knowledge to resolve.
+								</p>
+							</li>
+							<li>
+								<h2 class="font-bold">Errors in Descriptions</h2>
+								<p>
+									The short descriptions were extracted using imprecise heuristics.
+									There are many cases of leftover wikitext markup, or cut-off sentences.
+								</p>
+							</li>
+						</ul>
+						<br/>
+						<h1 class="text-lg font-bold">Some Possible Points of Confusion</h1>
+						<ul class="list-disc pl-4">
+							<li>
+								<h2 class="font-bold">Unexpected Images</h2>
+								<p>
+									Not all the images are well-suited for display. For example, many
+									birds have their heads cropped out. And some fish are shown in a
+									preserved form that is hard to recognise. And some moths are shown
+									alongside a more prominent plant, and are hard to see.
+								</p>
+							</li>
+							<li>
+								<h2 class="font-bold">Unexpected Search Results</h2>
+								<ul class="list-[circle] pl-4">
+									<li>
+										In the Complex tree, searching for 'orange', then pressing enter, brings up
+										a kind of butterfly, instead of a citrus plant. This is because suggestions
+										are not yet ordered by how well known the taxon is.
+									</li>
+									<li>
+										In some cases, a search might unexpectedly have no results. For example,
+										searching for 'golden retriever' brings up nothing. This is because
+										breeds of domestic dog are not considered separate species, but as
+										variant descendants of Canis familiaris.
+									</li>
