If the article is meant to walk someone through creating their own microservice, it begins to miss crucial code snippets in the `Accepting POST Requests` section. It doesn't point out that one should go back to the Cargo.toml file and add the `url` and `serde_json` crates (and possibly `serde` and `serde_derive`). Also, it's missing these crates in the point regarding updating the `use` statements. However, if the article is not meant to walk the reader through creating their own, but just to follow along from your git repository, then think about updating the article to have the repo url listed at the beginning. Good article, otherwise.
