#### Azure Blob Storage

Node-Red node to connect to Azure Blob Storage


Ex: 'msg.payload' -> filename that you need to upload. Ex: filename.txt

- Use `msg.payload` to send a file to save on Azure Blob Storage.

- This file must be in the same folder of Node-RED user directory - typically `~/.node-red`


## Installation

```
npm install -g node-red-contrib-azure-blob-storage


## How to Use
