+Connects the cluster to an external NFS server by creating a StorageClass and PersistentVolume. This is an infrastructure app — it has no pods or namespace, just cluster-scoped resources.
 
 ## Prerequisites
 
-You need an NFS server already running and exporting a path. To set one up on a host:
-
-```bash
-./setup-nfs-host.sh <host> <media-path>

-Example:
-
-```bash
-./setup-nfs-host.sh box-01 /srv/nfs
-```

-This SSHs into the host, installs `nfs-kernel-server`, and configures the export.
+You need an NFS server already running and exporting a path. Most home NAS devices (Synology, TrueNAS, QNAP, Unraid) support NFS exports out of the box. If you're using a Linux server, see [Setting Up an NFS Server](#setting-up-an-nfs-server) below.

+
+## Setting Up an NFS Server
+
+Wild Cloud does not manage the NFS server itself — it only connects to one. Below are quick-start instructions for common setups.
+
+### NAS Devices
+
+Most NAS devices have NFS support built in:
+
+- **Synology**: Control Panel > Shared Folder > Edit > NFS Permissions > Create rule allowing your cluster's subnet (e.g., `192.168.1.0/24`)
+- **TrueNAS**: Shares > Unix Shares (NFS) > Add > select dataset, configure network access
+- **QNAP**: Control Panel > Shared Folders > Edit Shared Folder Permission > NFS host access
+- **Unraid**: Shares > select share > NFS Security Settings > set to Public or add allowed hosts
+
+Note the IP/hostname and export path — those are what you'll enter as `host` and `mediaPath` in the NFS app config.
+
+### Linux Server
+
+Install the NFS server package, create the export directory, and add it to `/etc/exports`:
+
+```bash
+# Install (Debian/Ubuntu)
+sudo apt-get install -y nfs-kernel-server
+
+# Create the export directory
+sudo mkdir -p /srv/nfs/media
+sudo chmod 755 /srv/nfs/media
+
+# Add to exports (allow all hosts on local network)
+echo '/srv/nfs/media *(rw,sync,no_subtree_check,no_root_squash)' | sudo tee -a /etc/exports
+
+# Apply and start
+sudo exportfs -rav
+sudo systemctl enable --now nfs-server
+```
+
+### Verifying the Export
+
+From any machine on the network, confirm the export is visible:
+
+```bash
+showmount -e <nfs-server-ip>
+```
+
+You should see your export path listed. Once verified, add the NFS app, set `host` and `mediaPath` to match, and deploy.
