 - `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.

+## Translation Utility
+
+make.ts merges multiple language files into one for easy editing, then splits them back into separate files. This tool lets you:
+- find the original text without searching another file
+- automatically remove duplicate text to save space
+- sort your i18n files according to the official order
+
+### Usage
+
+1. Open `make.ts` and edit the `targetLangFiles` and the `workFile` fields, change `zh_cn` to your language. please notice that The `suffix` and `file` values must be unique.
+2. Run `./make.ts` (or `ts-node make.ts` / `deno make.ts`). The language files will be merged into the `workFile` location (e.g. `zh_cn.json`).
+3. Edit the output file.
+4. Run `./make.ts` again. If the workfile is newer than the other files, the script will write the changes back to the language files (at the locations specified by `targetLangFiles`).
+5. If you don't want a language to be written back, add `ro: true` to its entry in `targetLangFiles`.
