+# Localizing Secretive
+
+If you speak another language, and would like to help translate Secretive to support that language, we'd love your help!
+
+## Getting Started
+
+### Download Xcode
+
+Download the latest version of Xcode (at minimum, Xcode 15) from [Apple](http://developer.apple.com/download/applications/).
+
+### Clone Secretive
+
+Clone Secretive using [these instructions from GitHub](https://docs.github.com/en/repositories/creating-and-managing-repositories/cloning-a-repository).
+
+### Open Secretive
+
+Open [Sources/Secretive.xcodeproj](Sources/Secretive.xcodeproj) in Xcode.
+
+### Localize the Main App
+
+Navigate to [Secretive/Localizable](Sources/Secretive/Localizable.xcstrings). 
+
+<img src="/.github/readme/localize_sidebar.png" alt="Screenshot of Xcode navigating to the Localizable file" width="300">
+
+If your language already has an in-progress localization, select it from the list. If it isn't there, hit the "+" button and choose your language from the list.
+
+<img src="/.github/readme/localize_add.png" alt="Screenshot of Xcode adding a new language" width="600">
+
+Start translating! You'll see a list of english phrases, and a space to add a translation of your language.
+
+### Localize SecretAgent
+
+Navigate to [Secretive/Localizable](Sources/SecretAgent/Localizable.xcstrings). 
+
+<img src="/.github/readme/localize_sidebar_agent.png" alt="Screenshot of Xcode navigating to the Localizable file" width="300">
+
+Repeat the same steps from the process of localizing the main app.
+
