+# Clock
+
+Welcome to Clock on Exercism's Rust Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+
+## Instructions
+
+Implement a clock that handles times without dates.
+
+You should be able to add and subtract minutes to it.
+
+Two clocks that represent the same time should be equal to each other.
+
+You will also need to implement `.to_string()` for the `Clock` struct. We will be using this to display the Clock's state.  You can either do it via implementing it directly or using the [Display trait](https://doc.rust-lang.org/std/fmt/trait.Display.html).
+
+Did you implement `.to_string()` for the `Clock` struct?
+
+If so, try implementing the
+[Display trait](https://doc.rust-lang.org/std/fmt/trait.Display.html) for `Clock` instead.
+
+Traits allow for a common way to implement functionality for various types.
+
+For additional learning, consider how you might implement `String::from` for the `Clock` type.
+You don't have to actually implement this—it's redundant with `Display`, which is generally the
+better choice when the destination type is `String`—but it's useful to have a few type-conversion
+traits in your toolkit.
