+    # Waiter polls an API operation until a resource enters a desired
+    # state.
+    #
+    # @note The waiting operation is performed on a copy. The original resource remains unchanged
+    #
+    # ## Basic Usage
+    #
+    # Waiter will polls until it is successful, it fails by
+    # entering a terminal state, or until a maximum number of attempts
+    # are made.
+    #
+    #     # polls in a loop until condition is true
+    #     resource.wait_until(options) {|resource| condition}
+    #
+    # ## Example
+    #
+    #     instance.wait_until(max_attempts:10, delay:5) {|instance| instance.state.name == 'running' }
+    #
+    # ## Configuration
+    #
+    # You can configure the maximum number of polling attempts, and the
+    # delay (in seconds) between each polling attempt. The waiting condition is set
+    # by passing a block to {#wait_until}:
+    #
+    #     # poll for ~25 seconds
+    #     resource.wait_until(max_attempts:5,delay:5) {|resource|...}
+    #
+    # ## Callbacks
+    #
+    # You can be notified before each polling attempt and before each
+    # delay. If you throw `:success` or `:failure` from these callbacks,
+    # it will terminate the waiter.
+    #
+    #     started_at = Time.now
+    #     # poll for 1 hour, instead of a number of attempts
+    #     proc = Proc.new do |attempts, response|
+    #       throw :failure if Time.now - started_at > 3600
+    #     end
+    #
+    #       # disable max attempts
+    #     instance.wait_until(before_wait:proc, max_attempts:nil) {...}
+    #
+    # ## Handling Errors
+    #
+    # When a waiter is successful, it returns the Resource. When a waiter
+    # fails, it raises an error.
+    #
+    #     begin
+    #       resource.wait_until(...)
