-# NoN translation Repo :3
-## SFW and NSFW
-### SFW
-These are the lang files shiped into the NoN mod jar. They are SFW, meaning that they use 'liquid' instead of cum, 'energy' instead of heat etc
-### NSFW
-These are included in the lang files in the default pack and overwrite the keys that used liquid etc to now use cum, heat and so on.

+目前我们开了三个翻译版本：
 
-## Additional info
-As a reminder, please double check that things are really translation mistakes. Some keys might look wrong but make sense in the context so compare it to the english counterpart. Example:
+## zh_cn_sfw
+这是准备交付到 mod jar 层的内容，不应包含任何色情词汇。
 
-```json
-"item.needsofnature.accessory.tooltip.liquid_decay_reduced": "Cum decay %s",
-"item.needsofnature.accessory.tooltip.liquid_decay_increased": "Cum decay %s",
-```
-```json
-"item.needsofnature.accessory.tooltip.player_energy_gain.increased": "Heat buildup %s",
-"item.needsofnature.accessory.tooltip.player_energy_gain.reduced": "Heat buildup %s",
-```
-These might look incorrect but with `%s` inserted it will be things like 
-"Heat buildup -10%" and "Cum decay +25%" so keep that in mind when looking for errors.

+
+## zh_cn_nsfw_meme
+这是对 LongCha 翻译的保留，将单独打成 zh_cn_meme 的空动画包（应用此包将覆盖 zh_cn_nsfw 的部分进度描述以提高节目效果）
+- 为什么不使用资源包？由于 mod 的逻辑，动画包优先级高于资源包，导致资源包不可能覆盖动画包的内容。

+## 翻译工具
+
+`make.ts` 将多个跨版本的 lang json 文件合并为一个，并且按照顺序排列好，使得相同的字串排列在相邻的位置。
+- 还能找出相同的字符串并删掉覆盖层的内容，从而减少额外的行。
+- 同时，还会自动排序为官方 lang 文件顺序。
+
+### 使用方法
+1. 打开 `make.ts`，编辑 `targetLangFiles` and the `workFile` 两项
+2. 执行 `make.ts`（或者是 `ts-node make.ts` / `deno make.ts`），合并的语言文件会被输出到 `workFile` 变量的位置。
+3. 编辑输出的合并版文件
+4. 再次执行，脚本会根据时间戳决定改为将文件拆回去
+5. 如果你不想覆盖某个特定的文件，给对应项加上 `ro: true`
+6. 如果你不想自动合并重复行，加上环境变量 `KEEP_SAME_OVERRIDE_LINES`
 
-- `skin`, `player skin`, and `base skin` refer to a Minecraft character appearance or texture, never human tissue. Use the language's established Minecraft or gaming term.
-- `destroyed skin` and `ripped skin` refer to NoN's ripped-clothing appearance. Prefer wording about a damaged appearance, outfit, or clothing when a literal translation would imply bodily injury.
-- Keep filenames and paths such as `destroyed_skin.png`, `destroyed_skin_mask_%s.png`, and `config/needsofnature` unchanged.
-- Keep mod and project names such as `Quick Skin`, `Skin Overrides`, `CPM`, `Figura`, `NoFigura`, and `NoN` unchanged.
