+# Sum Of Multiples
+
+Given a number, find the sum of all the multiples of particular numbers up to but not including that number.
+
+If we list all the natural numbers up to but not including 20 that are
+multiples of either 3 or 5, we get 3, 5, 6 and 9, 10, 12, 15, and 18.
+
+The sum of these multiples is 78.
+
+Given a number, find the sum of the multiples of a given set of numbers,
+up to but not including that number.
+
+## Rust Installation
+
+Refer to the [exercism help page][help-page] for Rust installation and learning
+resources.
+
+## Writing the Code
+
+Execute the tests with:
+
+```bash
+$ cargo test
+```
+
+All but the first test have been ignored.  After you get the first test to
+pass, remove the ignore flag (`#[ignore]`) from the next test and get the tests
+to pass again.  The test file is located in the `tests` directory.   You can
+also remove the ignore flag from all the tests to get them to run all at once
+if you wish.
+
+Make sure to read the [Crates and Modules](https://doc.rust-lang.org/stable/book/crates-and-modules.html) chapter if you
+haven't already, it will help you with organizing your files.
+
