+**The second step** in deploying a Cozystack cluster is to install and configure a Kubernetes cluster.
 The result is a Kubernetes cluster installed, configured, and ready to install Cozystack.
 
 If this is your first time installing Cozystack, [start with the Cozystack tutorial]({{% ref "/docs/getting-started" %}}).
 
 ## Installation Options
 
+### Talos Linux (Recommended)
+
+For production deployments, Cozystack recommends [Talos Linux]({{% ref "/docs/guides/talos" %}}) as the underlying operating system.
+A prerequisite to using these methods is having [installed Talos Linux]({{% ref "/docs/install/talos" %}}).
+
 There are several methods to configure Talos nodes and bootstrap a Kubernetes cluster:
 
 -   **Recommended**: [using Talm]({{% ref "./talm" %}}), a declarative CLI tool, which has ready presets for Cozystack and uses the power of Talos API under the hood.
 -   [Using `talos-bootstrap`]({{% ref "./talos-bootstrap" %}}), an interactive script for bootstrapping Kubernetes clusters on Talos OS.
--   [Using talosctl]({{% ref "./talosctl" %}}), a specialized command line tool for managing Talos.
+-   [Using talosctl]({{% ref "./talosctl" %}}), a specialized command-line tool for managing Talos.
 -   [Air-gapped installation]({{% ref "./air-gapped" %}}) is possible with Talm or talosctl.
 
+### Generic Kubernetes
+
+Cozystack can also be deployed on other Kubernetes distributions:
+
+-   [Generic Kubernetes]({{% ref "./generic" %}}) — deploy Cozystack on k3s, kubeadm, RKE2, or other distributions.
+
 If you encounter problems with installation, refer to the [Troubleshooting section]({{% ref "./troubleshooting" %}}).
 
 ## Further Steps
