 # ABTEST in Paddle Serving
 
+([简体中文](./ABTEST_IN_PADDLE_SERVING_CN.md)|English)
+
 This document will use an example of text classification task based on IMDB dataset to show how to build a A/B Test framework using Paddle Serving. The structure relationship between the client and servers in the example is shown in the figure below.
