+# babel-plugin-check-es2015-constants
+
+Validate ES2015 constants (prevents reassignment of const variables).
+
+## Example
+
+**In**
+
+```js
+const a = 1;
+a = 2;
+```
+
+**Out**
+
+```bash
+repl: "a" is read-only
+  1 | const a = 1;
+> 2 | a = 2;
+    | ^
+```
+
+[Try in REPL](http://babeljs.io/repl/#?babili=false&evaluate=true&lineWrap=false&presets=es2015&experimental=false&loose=false&spec=false&code=const%20a%20%3D%201%3B%0Aa%20%3D%202%3B&playground=true)
+
+## Installation
+
+```sh
+npm install --save-dev babel-plugin-check-es2015-constants
+```
+
+## Usage
+
+### Via `.babelrc` (Recommended)
+
+**.babelrc**
+
+```json
+{
+  "plugins": ["check-es2015-constants"]
+}
+```
+
+### Via CLI
+
+```sh
+babel --plugins check-es2015-constants script.js
+```
+
+### Via Node API
+
+```javascript
+require("babel-core").transform("code", {
+  plugins: ["check-es2015-constants"]
+});
+```
+
+## Note
+
+This check will only validate consts. If you need it to compile down to `var` then you must also install and enable [`transform-es2015-block-scoping`](http://babeljs.io/docs/plugins/transform-es2015-block-scoping/).
