 first command will add this HAL (Hardware Abstraction Layer), the second is required for the `#[entry]` macro, and _panic-halt_ creates a simple panic function, which just halts.
 
-You'll also need to copy the cargo config file from the [repo](https://github.com/rp-rs/rp-hal-boards/blob/main/.cargo/config). It specifies the target and optimizing flags to the linker. You'll also need to copy [_memory.x_](https://github.com/rp-rs/rp-hal-boards/blob/main/memory.x) to your project root. This file tells the linker the flash and RAM layout, so it won't clobber the bootloader or write to an out of bounds memory address.
