+# TypeScript-Aurelia
+
+This generator creates TypeScript/JavaScript client that is injectable by [Aurelia](http://aurelia.io/).
+The generated Node module can be used in the following environments: 
+
+Environment
+* Node.js
+* Webpack
+* Browserify
+
+Language level
+* ES5 - you must have a Promises/A+ library installed
+* ES6
+
+Module system
+* CommonJS
+* ES6 module system
+
+It can be used in both TypeScript and JavaScript. In TypeScript, the definition should be automatically resolved via `package.json`. ([Reference](http://www.typescriptlang.org/docs/handbook/typings-for-npm-packages.html))
+
+### Installation ###
+
+`swagger-codegen` does not generate JavaScript directly. The generated Node module comes with `package.json` that bundles `typescript` and `typings` so it can self-compile during `prepublish` stage. The should be run automatically during `npm install` or `npm publish`. 
+
+CAVEAT: Due to [privilege implications](https://docs.npmjs.com/misc/scripts#user), `npm` would skip all scripts if the user is `root`. You would need to manually run it with `npm run prepublish` or run `npm install --unsafe-perm`. 
+
+#### NPM ####
+You may publish the module to NPM. In this case, you would be able to install the module as any other NPM module. It maybe useful to use [scoped packages](https://docs.npmjs.com/misc/scope).
+
+You can also use `npm link` to link the module. However, this would not modify `package.json` of the installing project, as such you would need to relink every time you deploy that project. 
+
+You can also directly install the module using `npm install file_path`. If you do `npm install file_path --save`, NPM will save relative path to `package.json`. In this case, `npm install` and `npm shrinkwrap` may misbehave. You would need to manually edit `package.json` and replace it with absolute path. 
+
+Regardless of which method you deployed your NPM module, the ES6 module syntaxes are as follows: 
+```
+import * as localName from 'npmName';
+import {operationId} from 'npmName';
+```
+The CommonJS syntax is as follows:
+```
+import localName = require('npmName');
+```
+
+#### Direct copy/symlink ####
+You may also simply copy or symlink the generated module into a directory under your project. The syntax of this is as follows:
+
+With ES6 module syntax, the following syntaxes are supported: 
+```
+import * as localName from './symlinkDir';
+import {operationId} from './symlinkDir';
+```
+The CommonJS syntax is as follows:
+```
+import localName = require('./symlinkDir')';
+```
