 And the tooltip will be displayed as "My Tooltip" !
+==== Adding dynamic values to translatable text ====
+Say you want the text to change based on some variable, like the current day and month.
+For a dynamic number, we put a %d where you want the number to show in the lang entry value, for example:
+<code JavaScript resources/assets/tutorial/lang/en_us.json>
+{
+  "item.tutorial.fabric_item.tooltip": "My Tooltip in day %d, and month %d"
+}
+</code>
+Then we pass the variables we use in our string by the order it appears in the text. First the day, then the month:
+<code java>
+int currentDay = 4;
+int currentMonth = 7;
+tooltip.add(new TranslatableText("item.tutorial.fabric_item.tooltip", currentDay, currentMonth));
+</code>
+And the tooltip will be displayed as "My Tooltip in day 4, and month 7".
+In order to pass a string, we use ''%s'' instead of ''%d''.
