Contribution：Official document notes

[李新婷]

Hello!
  I'm currently learning from zookeeper's official documents and taking 
notes(https://blog.csdn.net/moqianmoqian/category_11015863.html）. The notes are 
relatively simple (in Chinese). I feel that it can help others read the 
official documents and understand zookeeper, so I want to contribute these 
articles (updating) to more people through you.Thanks for reading my letter, 
look forward to your reply.
 Wish you happy every day!
