 # esp32-lora-library
-## What is it
-**esp32-lora-library** is a C component to be integrated into ESP32-IDF for sending and receiving data through a LoRa transceiver based on Semtech's SX127_ ICs.
-
-The library itself is based on sandeepmistry's **arduino-LoRa** (https://github.com/sandeepmistry/arduino-LoRa) library for Arduino.
+## Which is
+** esp32-lora-library ** is a C component to be integrated with ESP32-IDF to send and receive data through a LoRa transceiver based on Semtech's SX127_ ICs.
+The library is a fork of the **esp32-lora-library ** (https://github.com/Inteform/esp32-lora-library) library of Inteform for ESP32.
 
 ## How to install
-Simply clone the repository and copy the ```components/lora``` directory into your ESP-IDF project directory or into the ```components/``` path of your $IDF_PATH (it will be public to all your projects).
-You can then simply ```#include "lora.h"``` and use its functions.
-Using ```make menuconfig``` there will be LoRa Options to configure (like pin numbers)
