+2. Create a language file (e.g. `zh-TW.js`). The filename must be ISO language code: http://www.lingoes.net/en/translator/langcode.htm
+3. Run `npm run update-language-files`. You can also use this command to check if there are new strings to translate for your language.
 4. Your language file should be filled in. You can translate now.
 5. Translate `src/pages/Settings.vue` (search for a `Confirm` component with `rel="confirmDisableAuth"`).
 6. Import your language file in `src/i18n.js` and add it to `languageList` constant.
