We are working towards making exercises stand-alone. That is to say: no more generating READMEs on the fly. This will give maintainers more control over each individual exercise README, and it will also make some of the backend logic for delivering exercises simpler. The README template uses the Go text/template package, and the default templates generate the same READMEs as we have been generating on the fly. See the documentation in [regenerating exercise readmes][regenerate-docs] for details. The READMEs can be generated at any time using a new 'generate' command in configlet. This command has not yet landed in master or been released, but can be built from source in the generate-readmes branch on [configlet][].

# 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,

## Elm Installation
|
|
|
|
Refer to the [Exercism help page](http://exercism.io/languages/elm) for Elm
|
|
installation and learning resources.
|
|
|
|
## Writing the Code
|
|
|
|
The first time you start an exercise, you'll need to ensure you have the
|
|
appropriate dependencies installed.
|
|
|
|
```bash
|
|
$ npm install
|
|
```
|
|
|
|
Execute the tests with:
|
|
|
|
```bash
|
|
$ npm test
|
|
```
|
|
|
|
Automatically run tests again when you save changes:
|
|
|
|
```bash
|
|
$ npm run watch
|
|
```
|
|
|
|
As you work your way through the test suite, be sure to remove the `skip <|`
|
|
calls from each test until you get them all passing!
