+# Pagerino: **Application server**
+
+### Description
+
+Dockerized server communicating with Chirpstack (v4) and processing incoming data.
+
+### Features
+
+Current working and in-progress capabilities include:
+ - receiving uplinks
+ - sending downlinks
+ - logging messages and telemetery
+ - managing users, devices, messages and other objects
+ - accepting api requests
+
+### Configuration
+
+Can be found in server.env:
+**CHIRP_API_KEY** - used to get more detailed information about the network
+of devices from Chirpstack
+
+**MQTT_ADDRESS** - address for MQTT broker that manages uplinks & downlinks,
+do not change unless you reconfigure the chirpstack as well
+
+**MQTT_CLIENT_ID** - ID to use when communicating with broker, can be anything
+
+**MQTT_QOS** - quality of service level, leave at zero unless your network supports it
+
+**APP_ID** - ID of accessing application registred in Chirpstack
+
+**API_PORT** - port at which API is provided, this and its wrappers are the
+only way to officially communicate with the server
+
+The app requires some other shared variables from shared.env.
+If not present, provide the following:
+**LOG_PREFIX**
+**SERVER_NAME**
+**TIMEOUT** - used for establishing connections
+
+### Prerequisites
+
+The server communicates through ssl with MQTT and needs the following files
+generated from Chirpstack in the certs directory:
+- ca.pem
+- client.key
+- client.pem
+
+It uses Chirpstack's gRPC API, so it needs the compiled proto files into go in
+the src/app_comm/api directory.
+
+### Usage
+
+The server requires to be on the same docker network as MQTT broker and Chirpstack
+to properly function.
+
+To start have Chirpstack v4 running in detached state and execute:
+```docker compose up```
+

+# ChirpStack Docker example
+
+This repository contains a skeleton to setup the [ChirpStack](https://www.chirpstack.io)
+open-source LoRaWAN Network Server (v4) using [Docker Compose](https://docs.docker.com/compose/).
+
+**Note:** Please use this `docker-compose.yml` file as a starting point for testing
+but keep in mind that for production usage it might need modifications. 
+
+## Directory layout
+
+* `docker-compose.yml`: the docker-compose file containing the services
+* `configuration/chirpstack`: directory containing the ChirpStack configuration files
+* `configuration/chirpstack-gateway-bridge`: directory containing the ChirpStack Gateway Bridge configuration
+* `configuration/mosquitto`: directory containing the Mosquitto (MQTT broker) configuration
+* `configuration/postgresql/initdb/`: directory containing PostgreSQL initialization scripts
+
+## Configuration
+
+This setup is pre-configured for all regions. You can either connect a ChirpStack Gateway Bridge
+instance (v3.14.0+) to the MQTT broker (port 1883) or connect a Semtech UDP Packet Forwarder.
+Please note that:
+
+* You must prefix the MQTT topic with the region.
+  Please see the region configuration files in the `configuration/chirpstack` for a list
+  of topic prefixes (e.g. eu868, us915_0, au915_0, as923_2, ...).
+* The protobuf marshaler is configured.
+
+This setup also comes with two instances of the ChirpStack Gateway Bridge. One
+is configured to handle the Semtech UDP Packet Forwarder data (port 1700), the
+other is configured to handle the Basics Station protocol (port 3001). Both
+instances are by default configured for EU868 (using the `eu868` MQTT topic
+prefix).
+
+### Reconfigure regions
+
+ChirpStack has at least one configuration of each region enabled. You will find
+the list of `enabled_regions` in `configuration/chirpstack/chirpstack.toml`.
+Each entry in `enabled_regions` refers to the `id` that can be found in the
+`region_XXX.toml` file. This `region_XXX.toml` also contains a `topic_prefix`
+configuration which you need to configure the ChirpStack Gateway Bridge
+UDP instance (see below).
+
+#### ChirpStack Gateway Bridge (UDP)
+
+Within the `docker-compose.yml` file, you must replace the `eu868` prefix in the
+`INTEGRATION__..._TOPIC_TEMPLATE` configuration with the MQTT `topic_prefix` of
+the region you would like to use (e.g. `us915_0`, `au915_0`, `in865`, ...).
+
+#### ChirpStack Gateway Bridge (Basics Station)
+
+Within the `docker-compose.yml` file, you must update the configuration file
+that the ChirpStack Gateway Bridge instance must used. The default is
+`chirpstack-gateway-bridge-basicstation-eu868.toml`. For available
+configuration files, please see the `configuration/chirpstack-gateway-bridge`
+directory.
+
+# Data persistence
+
+PostgreSQL and Redis data is persisted in Docker volumes, see the `docker-compose.yml`
+`volumes` definition.
+
+## Requirements
+
+Before using this `docker-compose.yml` file, make sure you have [Docker](https://www.docker.com/community-edition)
+installed.
+
+## Importing device repository
+
+To import the [lorawan-devices](https://github.com/TheThingsNetwork/lorawan-devices)
+repository (optional step), run the following command:
+
+```bash
+make import-lorawan-devices
+```
+
+This will clone the `lorawan-devices` repository and execute the import command of ChirpStack.
+Please note that for this step you need to have the `make` command installed.
+
+**Note:** an older snapshot of the `lorawan-devices` repository is cloned as the
+latest revision no longer contains a `LICENSE` file.
+
+## Usage
+
+To start the ChirpStack simply run:
+
+```bash
+$ docker-compose up
+```
+
+After all the components have been initialized and started, you should be able
+to open http://localhost:8080/ in your browser.
+
+##
+
+The example includes the [ChirpStack REST API](https://github.com/chirpstack/chirpstack-rest-api).
+You should be able to access the UI by opening http://localhost:8090 in your browser.
+
+**Note:** It is recommended to use the [gRPC](https://www.chirpstack.io/docs/chirpstack/api/grpc.html)
+interface over the [REST](https://www.chirpstack.io/docs/chirpstack/api/rest.html) interface.
