I am missing something... ~/.aws/config and ~/.aws/credentials

[chandailrc]

Hello, I was trying to run examples from this repo. I do not have prior experience with AWS. I am using conda env on Ubuntu 22.04. As per instructions I have installed the package using pip install "amazon-textract-textractor[dev]". Everything got installed without any hitch. Now I wanted to try out the table extractor example. When I try to run: extractor = Textractor(profile_name="default")

I get the error: ProfileNotFound: The config profile (default) could not be found

I found a workaround in one of the issue post: changing the profile_name to region_name

extractor = Textractor(region_name='us-west-2')

document = extractor.analyze_document(
    file_source=image,
    features=[TextractFeatures.TABLES],
    save_image=True
)

Now when I proceed I get the error: NoCredentialsError: Unable to locate credentials

It seems I am missing the ~/.aws/config and ~/.aws/credentials files. Not sure how I was supposed to get them? Do I need to install the aws sdk first?
