 Remove all instances and the renderer itself. The canvas element will remain in the DOM.
 
+### .prepareAttribute(attribute)
+
+Dynamically override an attribute with the same logic that is used during initial creation of the instance. The function requires an object with a name, size and data attribute.
+
+> Note: The calculation of the data function is done on the CPU. Be sure to check for dropped frames with a lot of particles.
+
+Attributes can also be switched. In the demo this is used to continue with a new start position identical to the end position. This can be achieved with `.prepareBuffer(attribute)` in which the data function is replaced with the final array.
