-
-This is a fork of BullshitGenerator.
-
-This tool could encode (hide) any data into nonsense chinese text, to avoid the extreme censorship of chinese forum. 
-
-This tool should be used to decode data from nonsense chinese text. 
-
-此工具基于bullshit生成器，将任意数据encode在中文文章中，避免被审查和屏蔽。
-
-## Format proposal
-
-The first section encodes the topic. 
-
-The second section should use the bootstrap data.json and the topic above, to encode an url to actual data.json. 
-
-The third section is the actual data section.
