Welcome! We have a collection of demo apps written to help you get a head start

on your atPlatform journey. We recommend looking at the apps in the following

order:

1. `at_getting_started` : Learn the fundamental elements of the atPlatform. Cut your own cryptographic keys

    with at_activate. Then with at_put to send and at_get to receive asynchronous data. Then move on to near realtime communication with at_send and at_receive.

2. `at_rpc_demo` : Sample 'client' and 'server' programs which demonstrate

   the use of the AtRpc library in the

   [at_client](https://pub.dev/packages/at_client) package.

3. `at_notifications`: A demo using `.notify` and `.subscribe` to send/receive

   notifications in the atPlatform. Demo uses [at_client] as the core dependency

   to utilize the atProtocol and [at_onboarding_cli] to authenticate atSigns to

   their atServers. To begin, follow the steps outlined in

   the [README](./at_notifications/README.md) of at_notifications to get

   started!

4. You should also definitely check out the

   [at_talk](https://github.com/atsign-foundation/at_talk) repo which

   shows how to build a simple end-to-end encrypted messaging app with the

   atPlatform.

5. `qt_atsign_plant_demo` a demo of using Atsign's technology with Qt's QML in Python to remotely and securely control/monitor a plant from a Qt app involving 2 raspberry pis, 4 sensors, and 1 actuator. Check it out here: [qt_atsign_plant_demo](./qt_atsign_plant_demo/)

6. `sshnp_raspberrypi_demo`: A demo establishing an SSH connection between a

   Raspberry Pi 4 Model B and a client device without requiring any open ports

   on the host machine (not even port 22). To begin, follow the steps outlined

   in the [README](./sshnp_raspberrypi_demo/README.md) of sshnp_raspberrypi_demo

   to get started!

7. `sshnp_docker_demo`: A demo to establish an SSH connection between two

   Docker containers without requiring any open ports on the host machine (not

   even port 22). To begin, follow the steps outlined in

   the [README](./sshnp_docker_demo/README.md) of sshnp_docker_demo to get

   started!

We are super glad that you are beginning your journey as an atDev. We highly

recommend that you join our discord dev community for troubleshooting, dev

updates, and much more!
