* Improving some sentences
I have change some sentence to make if more clearly and easy to read.
Besides, there is no corresponding word for "markdown" in Chinese to express the same meaning. So I think "markdown文件" is better than "降价文件"(means files for a reduction in price).
* change to simplified Chinese and fix markdown
* Polished Chinese Translation for Readability
Changed the grammatical errors and corrected the usage of 你 vs 您 for consistency
