+# Integration into "The Things Stack Community Edition" aka "The Things Stack V3"
+
+To use the ESP32-Paxcounter in The Things Stack Community Edition you need an account to reach the console. Go to:
+- [The Things Stack Community Edition Console](https://console.cloud.thethings.network/)
+- choose your region and go to applications
+- create an application by clicking "**+ Add application**" and give it a id, name, etc.
+- create a device by clicking "**+ Add end device**"
+- Select the end device:  choose the Brand "**Open Source Community Projects**" and the Model "**ESP32-Paxcounter**", leave Hardware Version to "**Unknown**" and select your **Firmware Version** and **Profile (Region)**
+- Enter registration data: choose the **frequency plan** (for EU choose the recommended), set the **AppEUI** (Fill with zeros), set the **DeviceEUI** (generate), set the **AppKey** (generate), choose a **device ID** and hit "Register end device"
+- got to Applications -> "your App ID" -> Payload formatters -> Uplink, choose "**Repository**" and hit "Save changes"
+
+The "Repository" payload decoder uses the packed format, explained below. If you want to use MyDevices from Cayenne you should use the Cayenne payload decoder instead.
+
+# TTN Mapper
+
+If you want your devices to be feeding the [TTN Mapper](https://ttnmapper.org/), just follow this manual: https://docs.ttnmapper.org/integration/tts-integration-v3.html - different than indicated in the manual you can leave the payload decoder to "Repository" for the ESP32-Paxcounter and you are fine.

 # Payload format

@ -274,12 +292,16 @@ You can select different payload formats in `paxcounter.conf`:

 - [***CayenneLPP***](https://mydevices.com/cayenne/docs/lora/#lora-cayenne-low-power-payload-reference-implementation) generates MyDevices Cayenne readable fields

+**Decrepated information from the things network v2 >>**
+
 If you're using [TheThingsNetwork](https://www.thethingsnetwork.org/) (TTN) you may want to use a payload converter. Go to TTN Console - Application - Payload Formats and paste the code example below in tabs Decoder and Converter. This way your MQTT application can parse the fields `pax`, `ble` and `wifi`.

 To add your device to myDevices Cayenne platform select "Cayenne-LPP" from Lora device list and use the CayenneLPP payload encoder. 

 To track a paxcounter device with on board GPS and at the same time contribute to TTN coverage mapping, you simply activate the [TTNmapper integration](https://www.thethingsnetwork.org/docs/applications/ttnmapper/) in TTN Console. Both formats *plain* and *packed* generate the fields `latitude`, `longitude` and `hdop` required by ttnmapper. Important: set TTN mapper port filter to '4' (paxcounter GPS Port).

+**<< Decrepated information from the things network v2**
+
 Hereafter described is the default *plain* format, which uses MSB bit numbering. Under /TTN in this repository you find some ready-to-go decoders which you may copy to your TTN console:

+With these files, we can make a pull request at the lorawan-devices repo: https://github.com/TheThingsNetwork/lorawan-devices and hope to be included in the future. Cool thing about it would be that then the users need only to choose "Open Source Community Projects" from the vendor list and "EXP32-Paxcounter" as device and most of the compex things is taking care of (like choosing the right LoRaWAN version and installing the payload decoder).
