+# count:
+#
+#   This covers pretty much any time that a specific number of things
+#   is represented! It's sectioned... like an alignment chart meme...
+#
+#   First counting specific wiki objects, then more abstract stuff,
+#   and finally numerical representations of kinds of quantities that
+#   aren't really "counting", per se.
+#
+#   These must be filled out according to the Unicode Common Locale
+#   Data Repository (Unicode CLDR). Check out info on their site:
+#   https://cldr.unicode.org
+#
+#   Specifically, you'll want to look into the Plural Rules for your
+#   language. Here's a summary on what those even are:
+#   https://cldr.unicode.org/index/cldr-spec/plural-rules
+#
+#   CLDR's charts are available online! This should bring you to the
+#   most recent table of plural rules:
+#   https://www.unicode.org/cldr/charts/latest/supplemental/language_plural_rules.html
+#
+#   Counting is generally done with the "Type: cardinal" section on
+#   that chart - for example, if the chart lists "one", "many", and
+#   "other" under the cardinal plural rules for your language, then
+#   your job is to fill in the correct pluralizations of the specific
+#   term for each of those.
+#
+#   If you adore technical details or want to better understand the
+#   "Rules" column, you'll want to check out the syntax outline here:
