## 📜 History
Coming from Python, I loved the guidelines on how *idiomatic Python* looks like. I was inspired by the likes of Peter Norvig, who wrote amazing articles on [spellcheckers](https://norvig.com/spell-correct.html) and [sudoku solvers](https://norvig.com/sudoku.html); and, of course, the [Zen of Python](https://www.python.org/dev/peps/pep-0020/). For Rust, there is no such thing as the Zen of Python, however, so I started collecting my own resources.
The goal of this project is to create a peer-reviewed collection of articles/talks/repos, which teach idiomatic Rust style. It's a community project and you can contribute.
