# Welcome

This Administration Guide explains how Maica's Residential Aged Care Services (RACS) solution is built, configured, and integrated. It is written for administrators, implementers, and support staff who set the solution up and keep it running, rather than the staff who use it day to day.

Use it to understand the data model and architecture, configure the global rates and settings that drive billing, set up the Services Australia integration, and configure the reporting and reconciliation services. For how to carry out resident-facing tasks, see the companion User Guide.

## What's in this guide
