+
+Installing and updating [Sunshine](https://github.com/LizardByte/Sunshine) on Linux is getting easier. LizardByte now
+has two public [Cloudsmith](https://cloudsmith.io/~lizardbyte/repos/) repositories for our DEB and RPM packages:
+
+- The [stable repository](https://cloudsmith.io/~lizardbyte/repos/stable/) contains packages for official releases and
+  is the best choice for most users.
+- The [beta repository](https://cloudsmith.io/~lizardbyte/repos/beta/) contains packages for prereleases, making it a
+  convenient way to try upcoming changes.
+
+We are starting with Sunshine packages. Once a repository is configured, Sunshine can be installed and updated with
+the same package manager used for the rest of your system. Cloudsmith's setup script detects your supported Debian,
+Ubuntu, Fedora, or openSUSE release automatically.
+
+## Getting started with Sunshine
+
+Choose either the stable or beta repository below. You only need to configure one of them.
+
+### Debian and Ubuntu
+
+{% include tabs.html tabs=page.debian_repositories %}
+
+After configuring the repository, install Sunshine:
+
+```bash
+sudo apt update
+sudo apt install sunshine
+```
+
+### Fedora and openSUSE
+
+{% include tabs.html tabs=page.rpm_repositories %}
+
+After configuring the repository, install Sunshine with your distribution's package manager:
+
+{% include tabs.html tabs=page.rpm_installers %}
+
+Package availability depends on the distributions and releases currently supported by both Sunshine and Cloudsmith.
+See the [Sunshine installation documentation][sunshine-install] for the latest details.
+
+## GitHub release downloads are staying
+
+Cloudsmith is an additional installation option, not a replacement for GitHub releases. If you prefer to download a
+DEB or RPM directly, those packages will remain available from the
+[Sunshine releases page](https://github.com/LizardByte/Sunshine/releases), along with Sunshine's other release files.
+
+## An easier publishing option for developers
+
+Developers who publish their own DEB or RPM packages can use the reusable
+[LizardByte Cloudsmith Upload action](https://github.com/LizardByte/actions/tree/master/actions/cloudsmith_upload). It
+uses Cloudsmith's official tooling, recognizes the distribution and release from common package filenames, checks
+Cloudsmith's current distribution support, and can publish packages from a GitHub Actions workflow. The action is
+public and reusable outside LizardByte projects too.
+
+We hope the new repositories make Sunshine installation and updates feel more familiar on Linux, while keeping the
+manual download options that users already rely on.
