+### ES Features
+
+This repo comes with its own Babel build which includes all ES6 and Stage 2 and Stage 3 features by default, except for the ES6 library polyfills.
+
+If ES6 polyfills are desired it is advisable to import core-js libraries manually as needed.
+
+To use Stage 1 features, these need to be manually enabled via configuration:
+
+```javascript
+SystemJS.config({
+  meta: {
+    '*.js': {
+      babelOptions: {
+        stage1: true
+      }
+    }
+  }
+});
+```
+
+If running in NodeJS or browsers that have ES2015 support, ES2015 feature transpilation can be disabled similarly:
+
+```javascript
+SystemJS.config({
+  meta: {
+    '*.js': {
+      babelOptions: {
+        es2015: false
+      }
+    }
+  }
+});
+```
+
+This allows workflows that just support ES modules and stage proposal transforms.
