+.. *******************
+
+This module provides authentication tokens obtained from RFID cards via the NXP PN7160 NFC chip.
+
+It uses a modified *libnfc-nci* as external dependency to interface the chip via I²C or SPI, either from user space or via a kernel module.
+
+Hardware Interface Configuration
+================================
+
+Configuration of the hardware interface is possible at runtime.
+The module installs two configuration files:
+
+* ``libnfc-nci_config/libnfc-nci.conf``: define NFC options
+* ``libnfc-nci_config/libnfc-nxp.conf``: choose the hardware interface (kernel module vs. userspace; I²C vs. SPI, ...)
+
+Module Configuration
+====================
+
+The EVerest module can be adjusted in its behaviour as follows:
+
+* ``token_debounce_interval_ms``: Publish tokens in minimum intervall of this timespan in order not to flood subscribers.
+* ``disable_nfc_rfid``: Allows to load the module without actually initializing the hardware.
