 # LoRa Gateway for WUSN
 
-LoRa Gateway for WUSN (<https://github.com/ComNets-Bremen/WUSN/>)
+LoRa Gateway for WUSN, created by Daniel Helms <dhelms@uni-bremen.de>, https://github.com/B00mb0x/LoRa_Gateway_for_WUSN
+
+It is based on the PyCom boards / ESP32 with LoRa transceiver. https://pycom.io/
+
+## Versions
+
+This repository contains two versions of the gateway:
+
+1) **Deepsleep** is a Python based version which uses the deep sleep
+functionality. This version has a higher delay and should not be used for
+scenarios, where messages are sent frequently.
+
+2) **Lightsleep** is an Arduino-based version of the gateway. It requires more
+energy but also higher packet rates.
