 # Fission Node.js Examples
 
+This is V2 example, check [here](README_V1.md) for V1.
+
 This directory contains several examples to get you started using Node.js with Fission.
 
-## Environment
-
 Before running any of these functions, make sure you have created a `nodejs` Fission environment:
 
+```bash
+# Create an environment with default nodejs images
+$ fission env create --name nodeenv --image fission/node-env:latest --builder fission/node-builder:latest
+# Create zip file from our example
+$ zip -jr nodejs.zip nodejs/
+# Create a package with the zip file
+$ fission pkg create --sourcearchive nodejs.zip --env nodeenv
 ```
-$ fission env create --name nodejs --image fission/node-env
-```
-
-Note: The default `fission/node-env` image is based on Alpine, which is much smaller than the main Debian Node image (65MB vs 680MB) while still being suitable for most use cases.
-If you need to use the full Debian image use the `fission/node-env-debian` image instead.
-See the [official Node docker hub repo](https://hub.docker.com/_/node/) for considerations 
-relating to this choice.

 ## hello.js
 
 This is a basic "Hello, World!" example. It simply returns a status of `200` and text body.
 
 ### Usage
+Since it is an `async` function, you can `await` `Promise`s, as demonstrated in the `weather.js` function.
 
 ```bash
-# Upload your function code to fission
-$ fission function create --name hello --env nodejs --code hello.js
+# Create a function
+$ fission fn create --name hello --pkg [pkgname] --entrypoint "hello"

+## index.js
+
+This file does nothing but for demonstrating `require` feature.
+
+### Usage
+```bash
+# Create a function, you can skip `--entrypoint` as node will look for `index.js` by default
+$ fission fn create --name index --pkg [pkgname]
+
+# Test the function
+$ fission fn test --name index
+```
+
+## multi-entry.js
+
+This is a multiple exports example. There are two exports: entry1 and entry2
+
+### Usage
+```bash
+# Create a function for entry1
+$ fission fn create --name entry1 --pkg [pkgname]  --entrypoint "multi-entry.entry1"
+
+# Test the function
+$ fission fn test --name entry1

-## stock.js
-
-This is a basic example of how you can easily use asynchronous requests in your functions. By default, the Node.js environment makes the [`request-promise-native`](https://github.com/request/request-promise-native) library available. In this example, the Google Finance API is used to determine when a stock was last traded.
