+		<title>Welcome to APEX - The Adaptive Policy EXecution (Engine)</title>

+		<section name="Welcome to APEX - The Adaptive Policy EXecution (Engine)">
+
+			<p>
+				The APEX (Adaptive Policy Execution) policy engine is a fully featured policy engine that executes anything from simple to adaptive policies.
+				An adaptive policy is one that can modify its behavior based on the current conditions of the network and systems.
+				Adaptive policies have the following characteristics:
+				<ul>
+					<li>Are able to make decisions at runtime rather than simply selecting decisions described at policy definition time</li>
+					<li>Can use additional context information that was not provided in the incoming event or request</li>
+					<li>Can be adapted or self-adapt at runtime to modify decision making</li>
+				</ul>
+			</p>
+
+			<p>
+				The APEX policy engine accepts input events and requests from other components, routes the input to the appropriate policies, computes the policy results, and generates response events or actions to be processed by other components.
+				The policies may be affected by information injected into the policy context as changes in business or domain goals, by information derived from previous executions of the policies, and by context information retrieved from other components (analytics, inventory, topology, etc.).
+			</p>
+
+			<p>
+				APEX connects to a Trigger System to receive events that can trigger a policy and to an Actioning System to send the result of a policy.
+				The connection support various common technologies, such as messaging systems (Kafka, Websockets), file input/output, and standard input/output.
+				APEX supports context (as additional information) for all events as well as inside the engine to support policies.
+				Context information can be read from any outside source.
+			</p>
+
+			<p>
+				A policy is defined in a Universal Execution Policy Specification (UEPS), directly executable in an APEX engine.
+				Higher-level policy specifications (or existing policy languages) can be easily translated in UEPS.
+			</p>
+
+			<p>
+				An APEX system can use multiple policy engines with different policies deployed on each of them.
+				Context information is automatically shared between all engine instances.
+				A simple deployment component is provided.
+			</p>
