+# Secure EcmaScript (SES)
+
+Secure EcmaScript is a frozen environment for running EcmaScript 'strict'
+mode programs. These programs run without ambient authority in their global
+scope, and add safe two-argument evaluator (`SES.confine(code, endowments)`)
+to each realm. It runs atop an ES6-compliant platform, enabling safe
+interaction of mutually-suspicious code, using object-capabilities.
+
+See https://github.com/Agoric/TinySES to see how SES fits into the various
+flavors of confined EcmaScript execution.
