+	<Sec h={2} id="skills">Skills</Sec>
+	<p>
+		Relevant <Mono>text_data</Mono> categories include 47 for skill names and 48 for skill descriptions. Otherwise, info for skills
+		lives in <Mono>skill_data</Mono>.
+	</p>
+	<ul class="ml-4 list-disc pb-4">
+		<li>Skill ID is just <Mono>id</Mono>.</li>
+		<li>
+			<Mono>rarity</Mono> is 1 for common (white) skills, 2 for rare (gold) skills, 3 for 1&star;/2&star; uniques, 4 for 3&star; uniques
+			of horses upgraded from 1&star; or 2&star;, and 5 for full 3&star; uniques.
+		</li>
+		<li>
+			<Mono>group_id</Mono> groups skills that replace each other when purchased. E.g., <Skill skill={skills.fall1} />, <Skill
+				skill={skills.fall2}
+			/>, <Skill skill={skills.fallX} />, and <Skill skill={skills.fallR} />
+			all have a <Mono>group_id</Mono> of {fallGroup}. Unique skills are generally alone in their groups.
+		</li>
+		<li>
+			<Mono>group_rate</Mono> gives the relative strength of a skill within its group. Negative (purple) skills always have a <Mono
+				>group_rate</Mono
+			> of -1. For skills that have non-purple versions (i.e. not skills like <Skill skill={skills.g1Averse} />), the base version
+			has a <Mono>group_rate</Mono> of 1 and each successive upgrade is 1 higher. E.g., <Skill skill={skills.fall1} /> is 1, <Skill
+				skill={skills.fall2}
+			/> is 2, <Skill skill={skills.fallR} />, and <Skill skill={skills.fallX} /> is -1. Skills that have only common and rare versions
+			instead assign a <Mono>group_rate</Mono> of 2 to the rare.
+		</li>
+		<li>
+			<Mono>grade_value</Mono> is the amount the skill adds to a horse's rating when owned. Higher tiers of skills within a group replace
+			the lower ones rather than adding to them, so <Skill skill={skills.fall2} /> is worth its listed grade value of 174, not <Skill
+				skill={skills.fall1}
+			/>'s 129 plus 174.
+		</li>
+		<li>
+			<Mono>skill_category</Mono> gives the category where the skill is listed in the skills tab at the paddock:
+			<table class="table-fixed border text-center">
+				<thead>
+					<tr>
+						<th scope="col" class="px-2">Category ID</th>
+						<th scope="col" class="px-2">Category</th>

+							<td class="px-2">{name}</td>
+						</tr>
+					{/each}
+				</tbody>
+			</table>
+		</li>
+		<li>
+			<Mono>tag_id</Mono> gives a slash-separated list of three-digit tag values that various other mechanics can match against. E.g.,
+			Copano Rickey's unique skill <Skill skill={skills.rickey} /> counts the number of skills activated with tag values between 601
+			and 615 to determine the multiplier on its extra effects; mechanics like GL shop skills and MANT rivals match tags for running
+			style (101 to 104), distance (201 to 204), and/or surface (501 and 502); and I expect that support card unique effects like Mejiro
+			Ramonu will count "speed-increasing skills" by looking for tag 401.

+			unique.
+		</li>
+		<li><Mono>exp_type</Mono> appears to be 1 when the skill is able to gain levels, i.e. is a unique skill.</li>
+		<li><Mono>activate_lot</Mono> is 1 if the skill uses a wit check.</li>
+		<li><Mono>disp_order</Mono> is the sort order used in the skill purchase menu.</li>
