When cloning this repo and running
cargo build

I get this error:

Ahh, right. This is likely due to missing git submodules.

There's a note in the peerpiper-wallet but it should probably be moved up to the main repo

peerpiper/crates/peerpiper-wallet/README.md

Lines 17 to 32 in c8431a7

	## Cloning w/ links to external repos via git submodules
	The Wallet architecture makes it safe and easy to use other people's code, due to the sandboxing of WebAssembly. Thus, the code you want to use is likely in someone else's repository. We need their:
	1. *.wasm binary, and;
	2. *.wit file
	This crates uses [git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules) to link to those external repos so we can build from their source and link to their Wasm Interfaces (WIT).
	To clone this repo and the submodules use:
	```bash
	git clone --recurse-submodules
	```
	If you already cloned the project and forgot `--recurse-submodules`, you can combine the `git submodule init` and `git submodule update` steps by running `git submodule update --init`. To also initialize, fetch and checkout any nested submodules, you can use the foolproof `git submodule update --init --recursive`.

Oh wait, you might be running rust stable, you need to switch to the nightly toolchain

rustup toolchain install nightly
rustup default nightly

[DougAnderson444]

I should add the nightly as a rust-toolchain.toml requirement (done)
