### Amazon S3
To use [Amazon S3](https://aws.amazon.com/s3/) as a storage system, you must
install the `aws-sdk` package via npm:
`npm install aws-sdk`
Once you've done that, your config section should look like this:
```json
{
"type": "amazon-s3",
"bucket": "your-bucket-name",
"region": "us-east-1"
}
```
Authentication is handled automatically by the client. Check
[Amazon's documentation](https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/setting-credentials-node.html)
for more information. You will need to grant your role these permissions to
your bucket:
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"s3:GetObject",
"s3:PutObject"
],
"Effect": "Allow",
"Resource": "arn:aws:s3:::your-bucket-name-goes-here/*"
}
]
}
```
