  * `func` is the function to be executed. It can be any function that returns false when it needs to be called again in following game ticks (e.g. `AnimMove`). It could theoretically be any function, but usually you want to use one of the cinematic functions here.
  * `args` is a list containing the arguments that need to be passed to the function given, in the same order

+==== Animation ====
+
+An animation is a data structure that is a sequence of animation steps. It is specified as a table of steps. The steps will be executed in the specified order.
+
+==== Animation list ====
+
+The animation list is a list of all animations that were added but not performed so far. This is an internal table, you can not access it directly. You add to the list with `AddAnim`.
+
 === How animation works ===
 
 The Animation library has two states: *Animating* and *Not Animating*. By default, the game starts in the *Not Animating* state, meaning the game behaves normally. In *Animating* state, the library looks at the list of registered animations and executes them one by one, in that order.
@@ -83,7 +92,7 @@
 An optional convenience parameter `startAnimating` is available; if set to `true`, the game will start in “animation” mode which enables cinematic mode and disables all controls except precise for skipping. This is useful if you want to indicate that an animation will be played right at the start and the player must not be allowed to use any controls before the animation is over. If you set this parameter to `true`, you also *must* play at least one animation after this, otherwise the game will be stuck.
 
 ==== `AnimInsertStepNext(step)` ====
-Inserts `step` after the current step (read: action) in the cinematic array. Useful when an action depends on variables (e.g. positions). It can be used mostly with `AnimCustomFunction`. Note: In case of multiple consecutive calls, steps need to be added in reverse order.
