Subject: [PATCH] Update post 2 with beginner friendly cargo tips

As a relatively new person to Rust, I confused the `.cargo/config.toml` with the global cargo config in my home directory (`~/.cargo/config.toml). While this is pretty obviously wrong in hindsight, since I've never used the `[unstable]` options before, I didn't realize my mistake until this next thing that tripped me up.

For `cargo install bootimage`, I think it is reasonable to tell the reader to go into a different directory to execute the command, since it might be the case that the reader has never dealt with different targets before and would have no idea that running `cargo install` for the new target that they just made in a json would be wrong (at least this was me).

This could be worded differently than the changes I made, but I think that the addition of these could only benefit a confused reader.
