 If you speak another language, and would like to help translate Secretive to support that language, we'd love your help!
 
-## Getting Started
+## Crowdin
 
-### Download Xcode
+[Secretive uses Crowdin for localization](https://crowdin.com/project/secretive/). Open the link and select your language to translate!
 
-Download the latest version of Xcode (at minimum, Xcode 15) from [Apple](http://developer.apple.com/download/applications/).
+### Manual Translation
 
-### Clone Secretive
+Crowdin is the easiest way to translate Secretive, but I'm happy to accept Pull Requests directly as well.
-
-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!

 ### Auditable Build Process
 
-Builds are produced by GitHub Actions with an auditable build and release generation process. Each build has a "Document SHAs" step, which will output SHA checksums for the build produced by the GitHub Action, so you can verify that the source code for a given build corresponds to any given release.
+Builds are produced by GitHub Actions with an auditable build and release generation process. Starting with Secretive 3.0, builds are attested using [GitHub Artifact Attestation](https://docs.github.com/en/actions/concepts/security/artifact-attestations). Attestations are viewable in the build log for a build, and also on the [main attestation page](https://github.com/maxgoedjen/secretive/attestations).

 # Security Policy
 
+## Security Principles
+
+Secretive is designed with a few general tenets in mind:
+
+### It's Hard to Leak a Key Secretive Can't Read The Key Material
+
+Secretive only operates on hardware-backed keys. In general terms, this means that it should be _very_ hard for Secretive to have any sort of bug that causes a key to be shared, because Secretive can't access private key data even if it wants to.
+
+### Simplicity and Auditability
+
+Secretive won't expand to have every feature it could possibly have. Part of the goal of the app is that it is possible for consumers to reasonably audit the code, and that often means not implementing features that might be cool, but which would significantly inflate the size of the codebase.
+
+### Dependencies
+
+Both in support of the previous principle and to rule out supply chain attacks, Secretive does not rely on any third party dependencies. 
+
+There are limited exceptions to this, particularly in the build process, but the app itself does not depend on any third party code.
+
 ## Supported Versions
 
 The latest version on the [Releases page](https://github.com/maxgoedjen/secretive/releases) is the only currently supported version.
