 # Another Book on Data Science
 
-- The first three chapters (learn R and Python in Parallel) are finished.
-- For any questions, please open an issue for discussion.
+- This is the first book to talk about data science using R and Python in parallel, to my best knowledge.
+- I have finished 5 chapters, but for some reasons only chapter 1,2 and 4 are uploaded.
+- For any questions, please open an issue for discussion, or email me setseed2016@gmail.com.
