+An entity is the most common type of active game object in Aquaria.
+The following things are all implemented as entities:
+* Enemies, Bosses
+* Collectibles (Food, Ingredients, Treasures)
+* Objects that change size or position but that are not tiles, e.g. doors
+
+# Composition of an entity
+
+Graphically, an entity can be a simple sprite (`entity_setTexture()`) or a more advanced skeletal entity (`entity_initSkeletal()`) that can also be [[animated|animation-editor]].
+
+# In the editor
+
+[[Entity edit mode|editor-controls#entity-edit-mode-f6]] lists all keyboard shortcuts.
+
+# Scripting
+
+For scripting information, see [[Entity scripting|entity-scripting]]
