- Created README.md for Central setup documentation.
- Added dnsmasq configuration files and scripts for setting up DNS and PXE booting.
- Implemented nginx configuration to serve PXE boot assets.
- Developed setup.sh script to automate installation and configuration of dnsmasq and nginx.
- Removed outdated dnsmasq setup guide from documentation.

+# Central setup
+
+"Central" is a Wild-cloud concept for a network appliance use for cloud utilities.
+
+Right now, this is entirely `dnsmasq` to provide:
+
+- LAN DNS w/ forwarding of internal and external cloud domains to the cluster.
+- PXE for setting up cluster nodes.
+
+## Setup
+
+The setup is going through architecture design right now.
+
+- Initially, the process used to bootstrap a node was:
+  - Run `bin/install-dnsmasq` in your personal wildcloud dir to create a set of install files in `cluster/dnsmasq`.
+  - Copy this dir to a configured debian machine to have the services set up correctly as your Central.
+
+## Future setup
+
+To provide a better user experience, we have been creating a debian apt package that also does this while providing a UI.
+
+Development repo: https://github.com/civil-society-dev/wild-central
+
+The setup will look something like this:
+
+```bash
+# Download and install GPG key
+curl -fsSL https://mywildcloud.org/apt/wild-cloud-central.gpg | sudo tee /usr/share/keyrings/wild-cloud-central-archive-keyring.gpg > /dev/null
+
+# Add repository (modern .sources format)
+sudo tee /etc/apt/sources.list.d/wild-cloud-central.sources << 'EOF'
+Types: deb
+URIs: https://mywildcloud.org/apt
+Suites: stable
+Components: main
+Signed-By: /usr/share/keyrings/wild-cloud-central-archive-keyring.gpg
+EOF
+
+# Update and install
+sudo apt update
+sudo apt install wild-cloud-central
+```
+

-# Dnsmasq setup
-
-Steps:
-
-- Get some hardware. A $30 _Orange Pi Zero 3_ is good enough.
-- See [Armbian Setup](./armbian-setup.md).
-- From your wildcloud root, run `install-dnsmasq`. This will create the required installation files and copy them all to your dnsmasq server into `/tmp/dnsmasq-setup`.
-- ssh into your dnsmasq server and run `/tmp/dnsmasq-setup/setup.sh`.
