-## 🖥️ Compatibility
+### Firefox Versions
 
-Zen is currently built using Firefox version `138.0.3`! 🚀
+- [`Release`](https://zen-browser.app/download) - Is currently built using Firefox version `139.0.1`! 🚀
+- [`Twilight`](https://zen-browser.app/download?twilight) - Is currently built using Firefox version `RC 139.0.1`!
 
-- [`Zen Twilight`](https://zen-browser.app/download?twilight) - Is currently built using Firefox version `RC 138.0.3`!
-- Check out the latest [release notes](https://zen-browser.app/release-notes)!
-- Part of our mission is to keep Zen up-to-date with the latest version of Firefox, so you can enjoy the latest features and security updates!
+### Contributing
 
-## 🤝 Contribution
+If you'd like to report a bug, please do so on our [GitHub Issues page](https://github.com/zen-browser/desktop/issues/) and for feature requests, you can use [Github Discussions](https://github.com/zen-browser/desktop/discussions).
 
 Zen is an open-source project, and we welcome contributions from the community! Please take a look at the [contribution guidelines](./docs/contribute.md) before getting started!
-
-### Issue metrics
-
-We keep track of how many issues are closed at the end of the month in [docs/issue-metrics](./docs/issue-metrics). We use this to keep track of our issues and see our progress! 📈
-
-### Versioning
-
-Zen uses [Semantic Versioning](https://semver.org/), meaning versions are displayed as `a.b.cd` where:
-
-- `a` is the major version
-- `b` is the minor version
-- `c` is the branch prefix
-- `d` is the patch version
-
-### Branches
-
-Zen is divided into 2 main branches. We use `dev` for development and `stable` for stable releases. The `dev` branch is where all the new features are added and where `twilight` builds are generated. The `stable` branch is where the stable releases are generated.
-
-We divide into 2 branches in case there's any really important security update (for example) that needs to be released before the next stable release. This allows us to do patches without releasing unstable versions to the public.
-
-## 📥 Installation
-
-### Supported Operating Systems
-
-Zen is available for Linux, macOS, and Windows. You can download the latest version from the official website at [zen-browser.app](https://zen-browser.app/download), or from the [GitHub Releases](https://github.com/zen-browser/desktop/releases) page.
-
-If you don't see your OS listed below, that's because we already have it in our [downloads page](https://zen-browser.app/download)! Make sure to check it out!
-
-#### Windows

-```sh
-bash <(curl -s https://updates.zen-browser.app/install.sh)
-```
-
-- `AppImage` install:
-
-```sh
