+### Anisotropy values
+
+The anisotropy value is (value game wants + the set value); **Default** will use the native anisotropy value as it would be on hardware. **Automatic** sets it according to screen resolution. Turning off anisotropy is not recommended as it can break a myriad of games, however it is provided in the name of flexibility.
+
+Values from x2, x4, x8, x16, x32 up to x64 values are provided. This should be enough to not need to revise those values in my lifetime ever again.

 ### External
 
 While stock shaders offer a basic subset of options for most users, programs such as [ReShade](https://github.com/crosire/reshade) offer a more flexible experience. In addition to that users can also seek out modifications (mods) for enhancing visual experience (60 FPS mods, HDR, etc).

+# User Handbook - Native Application Development
+
+Debugging on physical hardware can get tedious and time consuming. Users are empowered with the debugging capabilities of the emulator to ensure their applications run as-is on the system. To the greatest extent possible atleast.
+
+## Debugging
+
+**Standard key prefix**: Allows to redirect the key manager to a file other than `prod.keys` (for example `other` would redirect to `other.keys`). This is useful for testing multiple keysets. Default is `prod`.
+
+**Changing serial**: Very basic way to set debug values for the serial (and battery number). Developers do not need to write the full serial as it will be writen in-place (that is, it will be filled with the default serial and then overwrite the serial from the beginning).
+- Battery serial: `YUZU0EMULATOR14022024`
+- Board serial: `YUZ10000000001`
+If the user were to set their board serial as `ABC`, then it will be written in-place and the resulting serial would be `ABC10000000001`. There are no underlying checks to ensure correctness of serials other than a hard limit of 16-characters for both.
