-WIP
+To create a gamerule, register it using the ''GameRuleRegistry'' of the Fabric API:
+<code java [enable_line_numbers="true"]>
+// Create and register a boolean game rule with the name "shouldPigsFly" which is true by default.
+public static final GameRules.Key<GameRules.BooleanRule> SHOULD_PIGS_FLY =
+GameRuleRegistry.register("shouldPigsFly", Category.MOBS, GameRuleFactory.createBooleanRule(true));
+</code>
+==== Using the gamerule ====
+To get access to the value of a game rule you need to get the server world:
+<code java [enable_line_numbers="true"]>
+world.getGameRules().getBoolean(SHOULD_PIGS_FLY)
+</code>
+==== Translation ====
+The registered gamerule now shows up untranslated in the game rule list, which can be opened in the world creation screen.
+To translate the name, add a ''gamerule.gameruleName'' entry (see [[tutorial:lang|lang]] for more info):
+<code json>
+{
+  "gamerule.shouldPigsFly": "Pigs should fly"
+}
+</code>
