-Shoryuken.configure_client do |config|
-  config.aws = {
-    secret_access_key: ...,         # or ENV["AWS_SECRET_ACCESS_KEY"]
-    access_key_id:     ...,         # or ENV["AWS_ACCESS_KEY_ID"]

-
-If you use Shoryuken with plain ruby worker class (not Rails), please call `configure_client` at the beginning of the worker file:
-
-```ruby
-Shoryuken.configure_client do |config|
-  config.aws = {
-    secret_access_key: ENV["AWS_SECRET_ACCESS_KEY"],
-    access_key_id:     ENV["AWS_ACCESS_KEY_ID"],
-    region:            ENV["AWS_REGION"]
-  }
-end
-
-class MyWorker
-end
-```
-
-The `aws` section is used to configure both the Aws objects used by Shoryuken internally, and also to set up some Shoryuken-specific config. The Shoryuken-specific keys are listed below, and you can expect any other key defined in that block to be passed on untouched to `Aws::SQS::Client#initialize`:
-
-- `account_id` is used when generating SNS ARNs
-- `sns_endpoint` can be used to explicitly override the SNS endpoint
-- `sqs_endpoint` can be used to explicitly override the SQS endpoint
-- `receive_message` can be used to define the options passed to the http://docs.aws.amazon.com/sdkforruby/api/Aws/SQS/Client.html#receive_message-instance_method
+There are a few ways to configure the AWS client:
 
-The `sns_endpoint` and `sqs_endpoint` Shoryuken-specific options will also fallback to the environment variables `AWS_SNS_ENDPOINT` and `AWS_SQS_ENDPOINT` respectively, if they are set.
-
-### Configuration (producer side)
-
-'Producer' processes need permissions to put messages into SQS. There are a few ways:
-
-* Use the `configure_server` in Rails initializer
 * Ensure the `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` env vars are set.
 * Create a `~/.aws/credentials` file.
 * Set `Aws.config[:credentials]` from Ruby code (e.g. in a Rails initializer)
 * Use the Instance Profiles feature. The IAM role of the targeted machine must have an adequate SQS Policy.
 
-For example, use the `configure_server` in `config/initializers/shoryuken.rb`:
-
-```ruby
-Shoryuken.configure_client do |config|
-  config.aws = {
-    secret_access_key: ENV["AWS_SECRET_ACCESS_KEY"],
-    access_key_id:     ENV["AWS_ACCESS_KEY_ID"],
-    region:            ENV["AWS_REGION"]
-  }
-end
-
-Shoryuken.configure_server do |config|
-  config.aws = {
-    secret_access_key: ENV["AWS_SECRET_ACCESS_KEY"],
-    access_key_id:     ENV["AWS_ACCESS_KEY_ID"],
-    region:            ENV["AWS_REGION"]
-  }
-end
-```
-
-
-Note that storing your credentials into Amazon instances represents a security risk. Instance Profiles tends to be the best choice.
