+# 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.

+PAGERINO(tm) WEB APPLICATION LICENSE AGREEMENT
+
+1. Parties & Purpose
+This License Agreement (“Agreement”) is entered into between GORAK Industries s.r.o., hereinafter “Licensor,” and [Client Name], hereinafter “Licensee,” for the use of the proprietary web application (“Software”) designed to work with specific provided and configured devices for the Pagerino(tm) system ("Devices").
+
+2. Intended Use
+The Software is designed for operation within a private local area network environment ("Environment") together with Devices and optimized for use in such a setting. If the Licensee chooses to expose the Software to external networks, use unathorized devices, use any parts of the Pagerino(tm) system in undocumented ways, the Licensee assumes full responsibility for any resulting risks, data breaches, performance degradation, or service interruptions. The Licensor is not liable for damages or losses arising from such use.
+
+3. Rights Granted
+Licensee may install and run the Software on approved internal servers and grant access to Licensee's authorized employees. Backup copies may be made for disaster recovery only. No rights are granted to modify, reverse-engineer, redistribute, rent, lease, or sublicense the Software.
+
+4. Ownership
+All intellectual property rights, including source code, remain the sole property of the Licensor. This Agreement does not transfer ownership of the Software or any associated rights, except the limited right to use as stated herein.
+
+5. Fees and Support
+The license fee covers the right to use the Software in its delivered state. Updates, upgrades, enhancements, and technical support are not included in the license fee and will be provided only under separate agreements and at prices determined by the Licensor’s company at the time of service. The Licensor is not obliged to provide updates or support unless explicitly agreed in writing.
+
+6. Limitations
+
+    The Software’s performance and accuracy depend on the network environment and the connected devices’ compliance with supported protocols.
+
+    The Licensor is not liable for malfunctions caused by third-party hardware, network configuration errors, incompatible devices, or environmental factors outside its control.
+
+    In case of system relocation, hardware replacement, or major infrastructure changes, reinstallation or reconfiguration support is considered a billable service.
+
+    If the Licensee modifies the Software without authorization, the Licensor may terminate the Agreement immediately.
+
+7. Liability
+The Software is provided “as-is.” To the maximum extent permitted under Czech law, the Licensor disclaims all warranties, whether express or implied, including fitness for a particular purpose. The Licensor’s liability for damages is limited to the amount actually paid for the license. Indirect, incidental, or consequential damages (including downtime, lost profits, or data loss) are excluded.
+
+8. Term & Termination
+This license is granted as perpetual, allowing the Licensee to use the Software for an unlimited time, subject to compliance with this Agreement. The Licensee’s right to use the Software may be terminated by the Licensor only if the Licensee breaches the terms of this Agreement. Upon termination, the Licensee must cease all use of the Software and destroy all copies in its possession.
+
+9. Governing Law & Jurisdiction
+This Agreement is governed by the laws of the Czech Republic. Any disputes will be resolved before the courts of Brno.
+
+10. Language & Final Provisions
+This Agreement may be provided in multiple languages. In case of discrepancies, the Czech version shall prevail. This document contains the entire agreement between the parties concerning the Software.

+# Pagerino: **Web server**
+
+### Description
+
+Dockerized server communicating with Pagerino applications to provide an interface.
+
+### Features
+
+Current working and in-progress capabilities include:
+ - list all devices
+ - add/modify/remove users, devices, roles and other objects
+ - see user, device, role and other's properties
+ - see live map view of devices
+
+### Usage
+
+The web app connects to other Pagerino applications after user authorization,
+so all of the accessed apps have to be running and reachable.
+
+First build the Tailwind css:
+```make css```
+
+Then to start the server with docker:
+```docker compose up```
+
+Alternatively you can just run it normally:
+```make go && make run```
+
+*Created by Olek \@ Gorak Industries*
