+# NOXOS Drivers API
+
+The API is directly baked into the kernel.
+The [libnxdrv](https://git.nerdcult.net/noxos/libraries/src/branch/master/libnxdrv) library provides dummies which can be (dynamically) linked into the driver.
+
+All API calls are prefixed with `nx_drv_`.
+
+# API
+## Config
+
+### struct `nx_drv_device_id_T`
+This struct is used to identify PCI and USB devices.
+

+# Drivers
+This is the documentation for the driver interface, not for the 'drivers' repo.
+
+Drivers are ELF executables which are dynamically linked into the kernel at runtime.
+A Driver can assign itself to PCI and USB devices or a Filesystem.
+PCI and USB device bindings are identified by their vendor and device ID.
+A Filesystem binding is identified by its MBR type and GPT type GUID.
+
+# Driver structure
+## Initialization
+A driver needs to have a function `void _init()` that will be called by the kernel when loading the driver.
+This function should handle the following things:
+- Load one or more __*configurations*__ (see API docs for more details)
+- Register __*handlers*__ (see API docs for more details)
+- Everything else the driver needs to initialize to be fully ready to be used (devices, etc.)
+
+## API
+Drivers communicate with the kernel using a runtime API.
+The documentation can be found [here](https://git.nerdcult.net/noxos/documentation/src/branch/master/drivers/API.md).
+
+## Handlers
+Drivers can register handler functions,
+that are called by the kernel when handling an action for an assigned device or filesystem.
+The documentation can be found [here](https://git.nerdcult.net/noxos/documentation/src/branch/master/drivers/handlers.md).
