 ## Introduction
 
-PaddleSlim is a sub-module of PaddlePaddle frame, which is first issued in the 1.4 version PaddlePaddle. In PaddleSlim, the mainstream compression strategies including pruning, quantization and distillation are realized and mainly applied to image compression models. In subsequent versions, more compression stratigies will be added to support models in NLP field.
