 ##### enabled | ``{isEnabled: boolean}``
 
+##### layer-added 
+
+##### layer-removed
+
+##### annotation-create | ``{object: fabric.Object}``
+Fires when annotation object is created. This does not apply when
+``annotation-replace`` is called - in that case, the replacement is
+considered as the creation.
+
+##### annotation-before-create | ``{object: fabric.Object, isCancelled: () => boolean, setCancelled: (cancelled: boolean) => void}``
+This event is fired prior to inserting any annotation, including promotion (simple helper annotation creation is not affected).
+`isCancelled` can be called to check if the deletion was already requested to be cancelled (by another plugin/module for example)
+`setCancelled` can be used to request to cancel the deletion
+
+##### annotation-delete | ``{object: fabric.Object}``
+
+##### annotation-before-delete | ``{object: fabric.Object, isCancelled: () => boolean, setCancelled: (cancelled: boolean) => void}``
+This event is fired prior to deleting any annotation.
+`isCancelled` can be called to check if the deletion was already requested to be cancelled (by another plugin/module for example)
+`setCancelled` can be used to request to cancel the deletion
+
+##### annotation-replace | ``{previous: fabric.Object, next: fabric.Object}``
+This event is fired when annotation is replaced, e.g. free-form-tool edit. Such edits
+in fact replace annotation with a new one, although the annotation identity as perceived
+by the user remains the same. This event is called only once per update, 
+at the end.
+
+##### annotation-before-replace | ``{object: fabric.Object, isCancelled: () => boolean, setCancelled: (cancelled: boolean) => void}``
+This event is fired prior to replacing annotation. Same usage as `annotation-before-delete`
+
+##### annotation-replace-doppelganger | ``{previous: fabric.Object, next: fabric.Object}``
+This event is fired when annotations are replaced, but only temporarily (e.g. via free form tool).
+It can be called several times during one edit action.
+
+##### annotation-before-replace-doppelganger | ``{object: fabric.Object, isCancelled: () => boolean, setCancelled: (cancelled: boolean) => void}``
+This event is fired prior to replacing doppelganger annotation. Same usage as `annotation-before-delete`
+
+##### annotation-edit | ``{object: fabric.Object}``
+This event is fired when user performs direct annotation editing.
+
+##### annotation-before-edit | ``{object: fabric.Object, isCancelled: () => boolean, setCancelled: (cancelled: boolean) => void}``
+This event is fired prior to editing annotation. Same usage as `annotation-before-delete`
+
+##### annotation-selected | ``{object: fabric.Object}``
+This event is fired when user selects an annotation.
+
+##### annotation-deselected | ``{object: fabric.Object}``
+This event is fired when user deselects an annotation.
+
+##### annotation-set-private | ``{object: fabric.Object}``
+This event is fired when the `private` property of an annotation changes.
+
+##### annotation-add-comment | ``{object: fabric.Object, comment: AnnotationComment}``
+This event is fired when a comment is added, one by one.
+```ts
+type AnnotationComment = {
+  id: string;
+  author: {
+    id: string;
+    name: string;
+  };
+  reference: string;
+  content: string;
+  replyTo?: string;
+  createdAt: number;
+  modifiedAt: number;
+  removed?: boolean;
+}
+```
+
+##### annotation-delete-comment | ``{object: fabric.Object, comment: AnnotationComment}``
+This event is fired when a comment is deleted, one by one.
+See `annotation-add-comment` for `AnnotationComment` definition.
+
+##### annotation-updated-comment | ``{object: fabric.Object, commentId: string, newComment: AnnotationComment | null}``
+This event is fired when comment data gets updated and is expected to re-render. `newComment` will be `null` if the comment was deleted.
+See `annotation-add-comment` for `AnnotationComment` definition.
+
 ##### comments-control-clicked
 This event is fired when user clicks the control for comments
