+## *gfx.particles* library
+
+```lua
+gfx.particles.emit(
+    -- emitter position: static coordinates or entity uid
+    origin: vec3 | int,
+    -- particle count (-1 - infinite)
+    count: int,
+    -- particle settings table
+    preset: table,
+    -- additional particle settings table
+    [optional] extension: table
+) -> int
+```
+
+Creates a particle emitter, returning its id.
+
+```lua
+gfx.particles.stop(id: int)
+```
+
+Stops the emitter permanently. The emitter will be deleted
+automatically later.
+
+```lua
+gfx.particles.is_alive(id: int) -> bool
+```
+
+Checks if the emitter is running. Returns false if it is stopped or if the emitter does not exist.
+
+```lua
+gfx.particles.get_origin(id: int) -> vec3 | int
+```
+
+Returns the static position or uid of the entity the emitter is bound to.
+
+Returns nil if the emitter does not exist.
+
+``lua
+gfx.particles.set_origin(id: int, origin: vec3 | int)
+```
+
+Sets the static position or uid of the entity the emitter will be bound to.

+# *rules* library
+
+```lua
+rules.create(
+    -- rule name
+    name: str,
+    -- default value
+    default: bool,
+    -- value change handler function
+    [optional] handler: function
+) -> int
+```
+
+Creates a rule. If a handler is specified, returns the id for deletion.
+
+> [!NOTE]
+> A rule is created by calling rules.create with a default value.
+> Rules that have not been created can be used, but resetting via rules.reset will result in setting the value to nil.
+
+```lua
+    rules.listen(
+    -- rule name
+    name: str,
+    -- value change handler function
+    handler: function
+) -> int
+```
+
+Adds a rule value change handler.
+
+Returns the id for deletion.
+Also allows subscribing to a rule before it is created.
+
+```lua
+rules.unlisten(name: str, id: int)
+```
+
+Removes a rule handler by id, if it exists.
+
+```lua
+rules.get(name: str) -> bool | nil
+```
+
+Returns the rule value, or nil if it has not been created yet.
+
+```lua
+rules.set(name: str, value: bool)
+```
+
+Sets the rule value by calling handlers. Can be used before
+creating a rule.
+
+```lua
+rules.reset(name: str)
+```
+
+Resets the rule value to the default value.
+
