How to maintain multiple AWS profiles for Serverless

Question

I have started using serverless.com for building and deploying my serverless functions to aws lambda. 
I have a different set of IAM credentials for this, When i try to configure those credentials i am getting following message from serverless

```sh
$serverless config credentials --provider aws --key BxxxxxxxxkeyxxxxxG --secret nxxxxxxxxxxxxxxxxxxxxxxxxx8
```

```sh
Serverless: Setting up AWS...
Serverless: Failed! ~/.aws/credentials already has a "default" profile. Use the overwrite flag ("-o" or "--overwrite") to force the update
```

How can i manage a different profile to manage the serverless?

You can maintain multiple aws profiles at this location `~/.aws/credentials` 
If you open it, you should see something like following

```sh
[default]
aws_access_key_id = AxxxxxxxxxxxxxxxQ
aws_secret_access_key = mxxxxxxxxxxxxxxxxxxxxxxx9
```

You can add multiple profiles here for example like following

```sh
[default]
aws_access_key_id = AxxxxxxxxxxxxxxxQ
aws_secret_access_key = mxxxxxxxxxxxxxxxxxxxxxxx9

[serverless-project1]
aws_access_key_id = AxxxxxxxxxxxxxxxQ
aws_secret_access_key = mxxxxxxxxxxxxxxxxxxxxxxx9

[s3-sync]
aws_access_key_id = AxxxxxxxxxxxxxxxQ
aws_secret_access_key = mxxxxxxxxxxxxxxxxxxxxxxx9
```
