+## Writing well-formatted code
+
+When you are solving the exercise, you are free to choose any coding format you want.
+However when you are writing a real-world application or a library, your source code will
+be read by other people, not just you. To solve a problem when different people choose
+different formats for a single project, the developers set a standard coding format
+for the said project.
+
+In the Rust world there is a tool, that helps developers to bring standard formatting
+to their applications - [rustfmt](https://github.com/rust-lang/rustfmt).
+
+To install `rustfmt` use the following commands:
+
+```bash
+rustup self update
+
+rustup component add rustfmt
+```
+
+After you have installed `rustfmt` and have solved the exercise, please consider
+using the following command inside the exercise directory to format your final solution:
+
+```bash
+cargo fmt
+```
