+a node v0.10 compatible build of [RE2JS]
+
+## install
+
+```sh
+npm i re2js-legendary
+```
+
+## usage
+
+usage instructions are the same as [RE2JS]
+
+## updating
+
+`index.cjs` and `index.cjs.map` are generated directly by [RE2JS] by running `npm i core-js@3`, using the following babel config, and then building:
+
+```js
+  presets: [
+    [
+      '@babel/preset-env',
+      {
+        targets: { 'node': '0.10' },
+        'useBuiltIns': 'usage',
+        'corejs': '3'
+      }
+    ]
+  ],
