+### How to use ng2-bootstrap in Angular2 with AoT compilation using ngc and rollup
+
+The compilation process is described on the official Angular2 website here: https://angular.io/docs/ts/latest/cookbook/aot-compiler.html
+
+Note that you also have to include bootstrap CSS from the official Bootrstrap site or Bootstrap CDN in your index.html HEAD section.
+
+#### 1) Install `ng2-bootstrap`
+
+```bash
+npm install ng2-bootstrap bootstrap --save
+```
+
+#### 2) Edit Angular 2 module
+
+Open the module file where you want to include ng2-bootstrap (most probably `app.module.ts`) and import either specific ng2-bootstrap modules by listing them in the import statement and then in the import array of the Angular 2 module
+
+```typescript
+import { AlertModule, ModalModule } from 'ng2-bootstrap/ng2-bootstrap';
+...
+
+@NgModule({
+   ...
+   imports: [AlertModule, ModalModule, ... ],
+   ... 
+})
+```
+
+ or use Ng2BootstrapModule to import all of the modules at once:
+
+```typescript
+import { Ng2BootstrapModule } from 'ng2-bootstrap/ng2-bootstrap';
+...
+
+@NgModule({
+   ...
+   imports: [Ng2BootstrapModule, ... ],
+   ... 
+})
+```
+
+#### 3) Edit rollup configuration (rollup-config.js)
+
+You have to use CommonJS rollup plugin, which you should be using anyway due to RxJS. If for some reason not, install it:
+
+```bash
+npm install rollup-plugin-commonjs --save --dev
+```
+
+Then you have to import the CommonJS plugin, include it in the plugins array and add ng2-bootstrap to the list of modules:
+
+```javascript
+...
+import commonjs from 'rollup-plugin-commonjs';
+...
+
+//paths are relative to the execution path
+export default {
+	...
+	plugins: [
+		...
+		commonjs({
+			include: [
+				'node_modules/rxjs/**',
+				'node_modules/ng2-bootstrap/**'
+			]
+		}),
+		...
+	]
+}
+```
+
+#### 4) Run compilation the standard way
+
+e.g.
+
+```bash
+ngc -p tsconfig-aot.json
+rollup -c rollup-config.js
+```
