 If you speak another language, and would like to help translate Secretive to support that language, we'd love your help!
 
-## Crowdin
+## Getting Started
 
-[Secretive uses Crowdin for localization](https://crowdin.com/project/secretive/). Open the link and select your language to translate!
+### Download Xcode
 
-### Manual Translation
+Download the latest version of Xcode (at minimum, Xcode 15) from [Apple](http://developer.apple.com/download/applications/).
 
-Crowdin is the easiest way to translate Secretive, but I'm happy to accept Pull Requests directly as well.
+### 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.
+
+### Translate
+
+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.
+
+### Create a Pull Request
+
+Push your changes and open a pull request. 
 
 ### Questions
 
 Please open an issue if you have a question about translating the app. I'm more than happy to clarify any terms that are ambiguous or confusing. Thanks for contributing!

 ### A Note Around Code Signing and Keychains
 
-While Secretive uses the Secure Enclave to protect keys, it still relies on Keychain APIs to store and access them. Keychain restricts reads of keys to the app (and specifically, the bundle ID) that created them. If you build Secretive from source, make sure you are consistent in which bundle ID you use so that the Keychain is able to locate your keys.
