+## ACRO-R: Statistical Disclosure Control
+
+ACRO is a free and open source tool that supports the semi-automated checking of research outputs (SACRO) for privacy disclosure within secure data environments. SACRO is a framework that applies best-practice principles-based statistical disclosure control (SDC) techniques on-the-fly as researchers conduct their analysis. SACRO is designed to assist human checkers rather than seeking to replace them as with current automated rules-based approaches.
+
+## What is ACRO-R?
+
+ACRO implements a principles-based statistical disclosure control (SDC) methodology that:
+
+* Automatically identifies potentially disclosive outputs
+* Applies optional disclosure mitigation strategies
+* Reports reasons for applying SDC
+* Produces summary documents for output checkers
+
+## Core Features
+
+### Semi-Automated Disclosure Checking
+
+* **Drop-in replacements** for common Python analysis commands (pandas, statsmodels, etc.) with configurable disclosure checks
+* **Automated sensitivity tests** : frequency thresholds, dominance (p%, NK rules, etc.), residual degrees-of-freedom checks
+* **Optional mitigations** : suppression, rounding, and more to come
+* **Session management** : track, rename, comment, remove, add exceptions, and finalise reports
+* **Configurable risk parameters** via YAML files
+* **Generates auditable reports** in JSON or Excel
+
+### Design Principles
+
+* **Free and open source** under MIT (ACRO) / GPLv3 (SACRO Viewer)
+* **Easy to install** via PyPI, CRAN, or GitHub; cross-platform (Linux, macOS, Windows)
+* **Familiar APIs** - same function signatures as native commands: acro.crosstab mirrors pandas.crosstab, etc.
+* **Comprehensive coverage** - tables, regressions, histograms, survival plots, etc.
+* **Transparent & auditable** - clear reports, stored queries, designed for human-checkers
+* **Configurable & extensible** - organisation-defined disclosure rules, multi-language support
+* **Scalable** - lightweight, session-based, local execution
