-## Roadmap
-- [x] Supports JSON and PHP translation files
-    - You can enable / disable file types in the config
-    - You can add your own custom file readers
-- [x] Supports multiple locales
-- [x] Supports parsing many code types
-    - Default: php, js and vue
-    - You can add more file extensions in the config
-- [x] [Unused Command](#unused-command)
-- [ ] Missing Command - _coming soon_
-- [ ] Orphaned Command - _coming soon_
-- [ ] Lint Command - _coming soon_
-    - This would run all of the other commands in a single command.
