-<p>
-AISA is an <b>implementation-neutral reference architecture</b> for building agentic AI systems.
-It formalizes how reasoning, execution, infrastructure, evaluation, and governance interact to
-produce <b>reliable, scalable, and auditable agent behavior</b>.

-<ul>
-  <li>🧱 <b>Architecture</b> — Layered system design for agentic AI</li>
-  <li>🧪 <b>Evaluation</b> — Trajectory-level testing and monitoring</li>
-  <li>🛡️ <b>Governance</b> — Policy enforcement, auditability, human oversight</li>

-<h2>How to Use AISA</h2>
+<p align="center" style="max-width:760px; margin:auto;">
+  The following diagram presents the high-level structure of AISA, showing how intelligence,
+  cognition, tooling, evaluation, deployment, and governance layers interact within an agentic system.
+</p>
 
-<ul>
-  <li>✔️ Design agentic systems with clear separation of concerns</li>
-  <li>✔️ Evaluate safety, reliability, and emergent behavior</li>
-  <li>✔️ Scale agentic solutions with governance built-in</li>
-</ul>
