* The [BkBasic](src/main/java/org/takes/http/BkBasic.java) class is a basic
implementation of the `Back` interface. It is responsible for accepting the
request from `Socket`, converting the socket's input to the
[Request](src/main/java/org/takes/Request.java), dispatching it to the
-provided [Takes](src/main/java/org/takes/Take.java) instance, getting
-the result and printing it to the socket's output until all the request is fulfilled.

* The [BkParallel](src/main/java/org/takes/http/BkParallel.java) class is
a decorator of the `Back` interface, that is responsible for running the
back-end in parallel threads. You can specify the number of threads or try
