To join the network and activate your paxcounter, you must configure either OTAA or ABP join method. You should use OTAA, whenever possible. To understand the differences of the two methods, [this article](https://www.thethingsnetwork.org/docs/devices/registration.html) may be useful.
-To join the network and activate your paxcounter, you have to configure either the preferred OTAA method or the ABP method. You should use OTAA, whenever possible. To understand the differences of the two methods, [this article](https://www.thethingsnetwork.org/docs/devices/registration.html) may be useful.
 
 To configure OTAA, leave `#define LORA_ABP` deactivated (commented). To use ABP, activate (uncomment) `#define LORA_ABP` in the file `src/loraconf.h`.

 ## src/ota.conf
 Create file `src/ota.conf` using the template [src/ota.sample.conf](https://github.com/cyberman54/ESP32-Paxcounter/blob/master/src/ota.sample.conf) and enter your WIFI network&key. These settings are used for downloading updates. If you want to push own OTA updates you need a <A HREF="https://bintray.com/JFrog">Bintray account</A>. Enter your Bintray user account data in ota.conf. If you don't need wireless firmware updates just rename ota.sample.conf to ota.conf.
