This readme is also visible from https://crates.io/crates/spin-sdk

We don't import anyhow::Result in the example above so I would remove this and change line 45 to:

async fn handle_hello_world(_req: Request) -> anyhow::Result<impl IntoResponse> {

Done!

Hi @rylev
Agreed, the README file is limited in what it explains to the user.
I have added a section that links to the developer documentation.

@tpmccallum I don't see the section linking to the developer docs. Where can I find that?

[tpmccallum]

Oh, my apologies @rylev (and good catch). It seems the backticks stopped the text from being an inline commit (and my changes were just added as general comments).

This is probably a blessing in disguise because it made me rethink where that paragraph should go for impact. I have placed the links to the developer documentation at the top of the file. Please approve if you like this approach so we can merge. Also, I am not sure how to make sure that these new changes are rendered on crates.io page (from memory, sometimes a new version bump and commit/merge to the crate is required, i.e. 0.0.N)

Left one comment with something we should address but other than that looks great!

Thanks so much for the review @rylev ; greatly appreciated!!!
