Installation steps is not clear

[pawan-yadav]

Hi Team, I am trying to integrate cloudsearchable gem with my existing project but installation steps are not clear, please add some step like where we will mention AWS credentails, how re-indexing will work etc.
I have tried with adding keys into initializer but not working

Aws.config.update({
   credentials: Aws::Credentials.new('your_access_key_id', 'your_secret_access_key')
})

Getting below error

Aws::CloudSearch::Errors::SignatureDoesNotMatch: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

Please help @philipmw
