All `crates`/`libraries` are in a `no-std` environment. This means we only have access to the [libcore](https://doc.rust-lang.org/core/) functionality.

Before jumping in, I highly recommend learning some stuff abotu **Rust** and embedded developmend with it.
A thorough series of steps might be:
1. Read through the [Rust Book](https://doc.rust-lang.org/book/)
2. Work through the [Interactive Rust Book](https://rust-book.cs.brown.edu/)
