+Kea Configuration Template: Home network of a power user
+========================================================
+
+This directory contains template configurations for home network of a power user.
+It may also be appropriate for a small office. It makes the following assumptions:
+
+- you want to use a single /24 class of IPv4 addresses
+- you want High Availability, so there are 2 DHCP servers
+- you have a handful of devices, and some of them (e.g. a printer or NAS) require
+  static addresses or extra options
+- you do not want to be bothered with database management
+- the setup is optimized for minimal-to-zero maintenance
+- performance is not an issue. You do not expect to see 100s of queries per second
+- you do not use IPv6
+- you do not want to update your DNS
+
+The logical set-up consists of two hosts, each running Kea DHCPv4 server and a Control
+Agent (CA). The server connects with the CA using UNIX sockets. Each DHCPv4+CA acts
+as one partner of the HA pair.
+
+```mermaid
+CA-1 ====== CA-2
+
+subgraph host1
+CA-1 ------ DHCPv4-1
+
+subgraph host2
+CA-2 ------ DHCPv4-2
+```
+
+Deployment Considerations
