How to: PreFlight Checks
* K9s uses 256 colors terminal mode. On `Nix system make sure TERM is set accordingly.

    ```shell
    export TERM=xterm-256color
    ```

* In order to issue resource edit commands make sure your EDITOR and KUBE_EDITOR env vars are set.

    ```shell
    # Kubectl edit command will use this env var.
    export KUBE_EDITOR=my_fav_editor
    ```

* K9s prefers recent kubernetes versions ie 1.28+
