+NF has a number of @ref macros that you can use in your debug builds to help you develop
+your application. These macros can log messages, throw errors, time functions, and pause
+the engine.

+nf::Vec3 pos = camera->getPosition();
+std::string posStr = std::to_string(pos.x) + (std::string)", " + std::to_string(pos.y) + (std::string)", " + std::to_string(pos.z);

 @section packagingTut Packaging and Distributing Your App
+
+@note Remember to only ever distribute your release build.
+
+The only external prerequisite when running a NF app is the 2022 64-bit MSVC
+redistributable. The installer is included in the `redist` folder in the engine download.
+
+Other than that, a build can be very simple:
+
+- **NFApp.exe** - The application binary which is named from the MSVC project
+- **assets** - The folder which holds your NFPacks
+  - **base.nfpack** - The NFPack that holds both critical and default assets
+
+These are the only files you need to package in your build.

+This page details NF's state system and how to use it.
+
+@section gamestatesOverview Overview
+
+Before your nf::Application is run, you must first construct every one of the gamestates
+you want to use in that app **on the heap**. This is because having gamestates with many
+objects could result in a stack overflow.
+
+~~~cpp
+YourState* state = new YourState;
+~~~
+
+When the nf::Application's destructor is called, `delete` is called on every added gamestate
+for your convenience.
 
 @section enterAndExit onEnter and onExit
 
+These two functions are meant to load / initialize and "reset" your state respectively.
+
+The `onEnter` function is called as the loading screen is shown. When it returns, the screen
+fades into your scene. If you do not specify a starting position or rotation for the `camera`,
+it will start at (0.0, 0.0, 0.0) facing -Z (forwards).
+
+The `onExit` function is different. How you use this function is up to you based off of
+what your states are and if you want to connect them in some way, but if you want a
+state to behave in the same way every time you start it, you must
+**reset scalar members of your state that `onEnter` doesn't set itself** and
+**also `delete` any dynamically created objects created while the state was runnng**.
