+# TypeScript-Babel Node
+
+This package enables Babel compilation of TypeScript compilation output through a registration function and a Node binary proxy.
+
+### Why do I want this?
+
+Because you want `ts-node` to run `async`/`await` code, but TypeScript will only compile `async`/`await` to ES6 and Node 5.x doesn't support all of ES6 yet. So you need Babel to bridge that gap.
+
+`ts-babel-node` wraps `ts-node` so you can do just that. Run the `ts-babel-node` executable exactly the same way you'd run `ts-node` and require `ts-babel-node/register` instead of `ts-node/register`.
+
+## Installation
+
+### Command Line
+
+To use `ts-babel-node` on the command line, install this package globally. Be sure to include whichever version of TypeScript you want to compile against.
+
+```
+$ npm install --global ts-babel-node [email protected]
+
+$ ts-babel-node my-file.ts
+```
+
+### Library
+
+To include `ts-babel-node` as a register function, install this package as a development dependency. Be sure to include whichever version of TypeScript you want to compile against.
+
+```
+$ npm install --save-dev ts-babel-node [email protected]
+```
+
+## Usage
+
+### Command Line
+
+Since `ts-babel-node` is a wrapper around `ts-node`, anything you can do with `ts-node` works with `ts-babel-node`. See [`ts-node`'s docs](https://github.com/TypeStrong/ts-node/#usage) for more details.
+
+### Library
+
+`ts-babel-node` exposes two APIs. The first is a wrapper around the `ts-node` API.
+
+```js
+// $ node this-file.js
+
+require('ts-babel-node').register(/* ts-node options */);
+// Or
+require('ts-babel-node/register');
+```
+
+You can also use this with the `--require ` option on `node`.
+
+```
+$ node --require ts-babel-node/register my-file.ts
+```
+
+The second API only adds the babel-compilation step. This is useful if your code is run from `ts-node`, as is the case in the [gulp](#gulp) scenario.
+
+```js
+// $ ts-node this-file.js
+
+require('ts-babel-node').registerBabel();
+// Or
+require('ts-babel-node/register-babel');
+```
+
+### Mocha
+
+```
+$ mocha --require ts-babel-node/register [...args]
+```
+
+### Tape
+
+```
+$ ts-babel-node node_modules/.bin/tape [...args]
+```
+
+### Gulp
+
+In your `gulpfile.ts` (note, `.ts`, not `.js`):
+
+```
+import 'ts-babel-node/register-babel';
+// ...
+```
+
+Then use `gulp` normally. Keep in mind that the babel traspiler won't be active in your `gulpfile.ts`, but will be running in all your imports.
