 ### Instructions:
 
-1. Main script: Run `bun config/translations/scan.ts` from the root directory.
-2. Observe translations being generated in all supported languages.
-  - Supported languages are localizations with general translation prompts:
-      - These prompts are directly found in `client/src/localization/prompts`.
\ No newline at end of file
+*All commands are run from the root directory.*
+
+**Supported languages are localizations with general translation prompts**
+- These prompts are directly found in `client/src/localization/prompts`.
+- If your language is missing, you can contribute by adding a new file in `client/src/localization/prompts` with the language code as the file name.

+0. Make sure git history is clean with `git status`.
+1. Install `hnswlib-node` package temporarily (we don't need to include it in the project):
+```bash
+npm install --save-dev hnswlib-node
+```
+2. Run `bun install`.
+3. Main script: Run `bun config/translations/scan.ts`.
+4. Observe translations being generated in all supported languages and saved in `client/src/localization/languages`.
+  - e.g.: `client/src/localization/languages/Es_missing_keys.json`
+5. Discard all git changes with `git checkout .`.
+6. Copy the generated translations to their respective files, e.g.: `client/src/localization/languages/Es.ts`.
