+# Zero To Production / Code
+
+This repository complements the [Zero To Production book](https://www.lpalmieri.com/posts/2020-05-24-zero-to-production-0-foreword/): it hosts snapshots of the codebase of our email newsletter project at end of each chapter.
+
+It is structured as a `cargo` workspace: running `cargo build` will build the codebase for **all** chapters.
+If you want to build/test/run the code for a _specific_ chapter, just move into its folder! E.g.:
+```bash
+# Run tests for the first part of Chapter 3
+cd chapter03-0
+cargo test
+```
+Alternatively, from the top-level folder, you can specify the binary you are interested into:
+```bash
+# Run the application as it is at end of the first part of Chapter 3
+cargo run --bin chapter03-0
+``
