 NX (Nrwl Extensions) is a set of libraries and schematics for the Angular framework.
 
+## Installing
+
+Add the following dependencies to your project's `package.json` and run `npm install`:
+
+```
+{
+  dependencies: {
+    "@ngrx/store": "4.0.2",
+    "@ngrx/effects": "4.0.2",
+    "@nrwl/nx": "https://github.com/nrwl/nx-build" 
+  }
+}
+```
+
+
+
 ## Schematics
 
+### addNgRxToModule
+
+#### Root
+
+Run `schematics @nrwl/nx:addNgRxToModule --module=src/app/app.module.ts  --root`, and you will see the following files created:
+
+```
+/src/app/+state/app.actions.ts
+/src/app/+state/app.effects.ts
+/src/app/+state/app.effects.spec.ts
+/src/app/+state/app.init.ts
+/src/app/+state/app.interfaces.ts
+/src/app/+state/app.reducer.ts
+/src/app/+state/app.reducer.spec.ts
+```
+
+Also, `app.module.ts` will have `StoreModule.forRoot` and `EffectsModule.forRoot` configured.
+
+#### EmptyRoot
+
+Run `schematics @nrwl/nx:addNgRxToModule --module=src/app/app.module.ts  --emptyRoot` to only add the `StoreModule.forRoot` and `EffectsModule.forRoot` calls.
+
+#### Feature
+
+Run `schematics @nrwl/nx:addNgRxToModule --module=src/app/mymodule/mymodule.module.ts `, and you will see the following files created:
+
+```
+/src/app/mymodule/+state/app.actions.ts
+/src/app/mymodule/+state/app.effects.ts
+/src/app/mymodule/+state/app.effects.spec.ts
+/src/app/mymodule/+state/app.init.ts
+/src/app/mymodule/+state/app.interfaces.ts
+/src/app/mymodule/+state/app.reducer.ts
+/src/app/mymodule/+state/app.reducer.spec.ts
+```
+
+Also, `mymodule.module.ts` will have `StoreModule.forFeature` and `EffectsModule.forFeature` configured.
+
+#### skipImport
+
+Add `--skipImport` to generate files without adding imports to the module.
+
+
+
