Setting up
On first launch Post asks whether you have a vault. If you keep one in Obsidian, Post shows you where to find it; any other folder of notes works too; and if you have none, Post makes one on your iPhone. It reads how your daily notes are named from your vault's settings, and sends a first note so you can see where notes will go. You can change where notes go later in Settings.
A note didn't arrive
If your vault can't be reached, notes wait safely on your phone and file themselves when it can be. Settings shows anything still waiting.
