+### Entitlement Agent
+
+This is a java agent that instruments sensitive class library methods with calls into the `entitlement-runtime` module to check for permissions granted under the _entitlements_ system.
+
+The entitlements system provides an alternative to the legacy `SecurityManager` system, which is deprecated for removal.
+With this agent, the Elasticsearch server can retain some control over which class library methods can be invoked by which callers.
+
+This module is responsible for inserting the appropriate bytecode to achieve enforcement of the rules governed by the `entitlement-runtime` module.
+
+It is not responsible for permission granting or checking logic. That responsibility lies with `entitlement-runtime`.
