[maartinj]

What it Does

• https://github.com/mikaelacaron/Basic-Car-Maintenance/issues/7
• App can use Polish translation

How I Tested

• Run the application in simulator with language set to Polish
• Checked screens that show proper Polish translation

Notes

• May need further updates as more features are developed where new strings will be available
