Feature Request: App first time launch walk-through

[linagee]

When I first launched the app, I had a background in how LoRa works and I had a rough idea of what to expect. I recently watched a Ham radio YouTuber demo Meshtastic and it seems even he really didn't understand some of the fundamentals of how the Meshtastic app works. He did not seem to get that the QR code stores the frequency, spreading factor, channel name, and encryption key.

The Meshtastic app could really use a "first time launch walk-through" where a few features are explained from a high level for first time users.

A few ideas on my mind:

• Link to the Meshtastic documentation somehow.
• Link to the buying opportunity for Meshtastic compatible devices if there is no device found after a few minutes. (Amazon searches can be affiliate links! Circle it back to Geeksville Industries LLC to help grow.) Example: https://amzn.to/314m7yZ Not sure if there is already a link in the documentation, I didn't see one. (Obviously selling devices to users carries a different set of risks than just linking to vendors or even search terms of compatible devices.)
• Explain that the QR code carries the frequency/spreading factor/channel name/encryption key info somehow in a friendly way.
• Wireless sharing is very nice, is there a way to promote that to be the primary option? Link sharing wouldn't work without internet.
• Somehow remind users that they might have to wake up their nodes if they are battery powered. (Especially if settings are trying to be pushed and there is no node connected and the app appears to freeze.)
• Somehow educate users that this is a really low bandwidth system, and pushing video over it is not feasible.
• Discourage use of "Long range / Slow". I think most people might confuse this with "Of course I want long range!" (and not understand that LoRa has a HUGE link budget and SF7 works for many applications, especially if you have mesh nodes all over.) Maybe present an "are you sure?" popup explaining that even "Short range / Fast" can go miles with line of sight. (Allow the user to do it anyway, I'm just saying there should be education there.)
• Explain that Meshtastic is much better than goTenna because it's open source and you can modify it however you like! (Also, goTenna has much worse signal range because it's not LoRa.)
