+\defgroup feature_savemgr Save data
+\ingroup feature
+\brief Functions to persistently store and retrieve arbitrary values
+
+The SaveManager may be used to persistently store game state such as player
+progress, statistics, achievements, etc. It works like a key-value store, where
+the key is a string and the value is an arbitrary type.
+
+SaveManager implements the following:
+
+- Storage and retrieval of primitive types and strings.
+- Automatic initialization of the database using default values.
+- The underlying database format is journaled, which reduces the likelihood of
+	players losing save data when an unexpected crash occurs while the SaveManager
+	is writing to disk.
+
+\see SaveManager
+
+\par Example
+
+The SaveManager instance reference may be retrieved by calling \c
+get_save_manager(). This function is available---
+
+- Within (derivatives of) Script
+
+- \todo Within (derivatives of) Scene
+
+- \todo As a public member function of LoopManager
+
+```cpp
+// Retrieve save manager
+crepe::SaveManager & save_manager = get_save_manager();
+```
+
+SaveManager may be used *explicitly*, using the \ref SaveManager::set "set()",
+\ref SaveManager::get "get()" and  \ref SaveManager::has "has()" methods:
+```cpp
+// Check if the key "foo" exists, and initialize it to 3 if it doesn't
+if (!save_manager.has("foo"))
+	save_manager.set<int>("foo", 3);
+// Get value of key "foo"
+int foo = save_manager.get<int>("foo");
+
+// ~~~ arbitrary game code ~~~
+foo += 10;
+// ~~~ arbitrary game code ~~~
+
+// Save "foo" back to database
+save_manager.set<int>("foo", foo);
+```
+
+Alternatively, SaveManager::get may be called with a default value as second
+parameter. This changes its return type to ValueBroker, which acts as a
+read/write handle to the specific key requested, and remembers the key and its
+value type for you:
+```cpp
+// Get a read/write handle to the value stored in key "foo", and initialize it
+// to 3 if it doesn't exist yet
+ValueBroker foo_handle = save_manager.get<int>("foo", 3);
+int foo = foo_handle.get();
+
+// ~~~ arbitrary game code ~~~
+foo += 10;
+// ~~~ arbitrary game code ~~~
+
+// Save back to database
+foo_handle.set(foo);
+```
+
+To further simplify game code, the return value of SaveManager::get may be
+implicitly cast to Proxy instead of ValueBroker. This allows the database value
+to be used as if it were a regular variable. This usage is detailed separately
+in \"\ref feature_proxy\".

+\defgroup feature_scene Scenes
+\ingroup feature
+\brief User-defined scenes
+
+Scenes can be used to implement game environments, and allow arbitrary game
+objects to be organized as part of the game structure. Scenes are implemented as
+derivative classes of Scene, which are added to the game using the SceneManager.
+Scenes describe the start of a Scene and cannot modify GameObjects during
+runtime of a Scene (use \ref feature_script for this purpose).
+
+\see SceneManager
+\see GameObject
+\see Script
+\see Scene
+
+\par Example
+
+This example demonstrates how to define and add scenes to the loop/scene manager
+in the `crepe` framework. Each concrete scene should be derived from Scene. In
+the example below, the concrete scene is named MyScene. A concrete scene should,
+at least, implement (override) two methods, namely load_scene() and get_name().
+The scene is build (using GameObjects) in the load_scene() method. GameObjects
+should be made using the component_manager::new_object().
+
+In the example below, two GameObjects (named object1 and object2) are added to
+MyScene. object1 and object2 do not have any non-default Components attached to
+them, however, if needed, this should also be done in load_scene(). Each
+concrete scene must have a unique name. This unique name is used to load a new
+concrete scene (via a Script). The unique name is set using the get_name()
+method. In the example below, MyScene's unique name is my_scene.
+
+After setting up one or more concrete scene(s), the concrete scene(s) should be
+added to the loop/scene manager. This is done in your main(). Firstly, the
+LoopManager should be instantiated. Than, all the concrete scene(s) should be
+added to the loop/scene manger via loop_mgr::add_scene<>(). The templated
+argument should define the concrete scene to be added.
+
+```cpp
+#include <crepe/api/Engine.h>
+#include <crepe/api/Scene.h>
+
+using namespace crepe;
+
+class MyScene : public Scene {
+public:
+	void load_scene() {
+		GameObject object1 = new_object("object1", "tag_my_scene", vec2{0, 0}, 0, 1);
+		GameObject object2 = new_object("object2", "tag_my_scene", vec2{1, 0}, 0, 1);
+	}
+
+	string get_name() const { return "my_scene"; }
+};
+
+int main() {
+	Engine foo;
+	
+	// Add the scenes to the loop manager
+	foo.add_scene<MyScene>();
+
+	return foo.main();
+}
+```

+\brief Create a concrete Script and attach it to a GameObject
+
+Scripts can be used to implement game behavior, and allow arbitrary code to run
+as part of the game loop. Scripts are implemented as derivative classes of
+Script, which are added to \ref GameObject "game objects" using the \ref
+BehaviorScript \ref Component "component".
+
+\see Script
+\see BehaviorScript
+\see GameObject
+
+\par Example
+
+\note This example assumes you already have a GameObject. If not, read
+\"\ref feature_gameobject\" first.
+
+First, define a class (anywhere) that inherits from Script. The Script class
+acts as an interface, and has three functions (\ref Script::init "\c init()",
+\ref Script::fixed_update "\c fixed_update()" and \ref Script::frame_update
+"\c frame_update()"), which *may* be implemented (they are empty by default).
+From now on, this derivative class will be referred to as a *concrete script*.
+
+```cpp
+#include <crepe/api/Script.h>
+#include <crepe/api/BehaviorScript.h>
+
+class MyScript : public crepe::Script {
+	void init() {
+		// called once
+	}
+
+	void fixed_update(crepe::duration_t delta_time) {
+		// called on fixed update
+	}
+	void frame_update(crepe::duration_t delta_time) {
+		// called for every rendered frame
+	}
+};
+```
+
+After defining a concrete script, it can be instantiated and attached to \ref
+feature_gameobject "game objects" during \ref feature_scene
+"scene initialization" using a BehaviorScript component:
+
+```cpp
+using namespace crepe;
+GameObject obj;
+
+// Create a BehaviorScript component to hold MyScript
+BehaviorScript & behavior_script = obj.add_component<BehaviorScript>();
+
+// Instantiate (and attach) MyScript to behavior_script
+behavior_script.set_script<MyScript>();
+```
+
+The above can also be done in a single call for convenience:
+```cpp
+obj.add_component<BehaviorScript>().set_script<MyScript>();
+```

+\brief ECS Components
+
+Components are attached to GameObject instances and are composed by the game
+programmer to create specific entities in the game world. While they are
+implemented as C++ classes, components should be treated as C-style structs,
+meaning all members are public and they do not contain functions.
+
+A basic component has the following structure:
+```cpp
+#include <crepe/Component.h>
+
+class MyComponent : public crepe::Component {
+public:
+	// Add your custom component's ininitializer properties after the `id`
+	// parameter. The first parameter is controlled by GameObject::add_component,
+	// while all other parameters are forwarded using std::forward.
+	MyComponent(game_object_id_t id, ...);
+
+	// Optionally define the `get_instances_max` method to limit the amount of
+	// instances of this component per GameObject. The default implementation for
+	// this function returns -1, which means the instance count does not have an
+	// upper limit:
+	virtual int get_instances_max() const { return -1; }
+
+	// Properties
+	// ...
+};
+```
+
+Generally, components are "handled" by \ref internal_system "systems", which may
+optionally change the components' state. Components' state may also be
+controlled by the game programmer through \ref feature_script "scripts".
