 # Just Drop It
+
 [![Build Status](https://travis-ci.org/Orange-OpenSource/just-drop-it.svg?branch=master)](https://travis-ci.org/Orange-OpenSource/just-drop-it)
 
 just-drop-it allows you to simply and instantly send a file to a friend, whatever your network configuration (proxies, VPN, and such). Just open your browser, drop the file in it and send the generated link to your friend : the file will be beamed to him without being stored on any platform.
 
 ### why would anyone do this?
-We thought that this kind of tool was missing in our work environment, so we tried to set one up. Lucky for us, tools like [node.js](https://nodejs.org/), [Express](http://expressjs.com/), [socket.IO](http://socket.io/) and [socket.IO-stream](https://github.com/nkzawa/socket.io-stream) made it quite easy to get something up and running.

 ## How to use it
-It couldn't be more simple (but you will need a running  instance of just-drop-it. If you don't have one see [the section below](##how-to-run-it) or wait for our online demo (*if a few days, we promise* :grin:)
 
-- open your just-drop-it in your browser 
-- drop your file (*just one please*)

 ## How to run it
 
 ### On any computer
-#### With node JS
-Download and install [node.js](https://nodejs.org/download/). Then:
-* Download the source code
-* Download the needed dependencies (first time only): `npm install` 
-* Start node-js server: `npm start` (to start the server in dev mode wit hot reload: `npm run start-dev`)

 - Run the image (first time): `docker run --name just-drop-it -p 8080:8080 -d  just-drop-it` (next time you will just have to start it with `docker start just-drop-it`)

 ### Framework

 To meet the requirements, we chose the followings:

+- [Node.js](https://nodejs.org/)
 - [Express](http://expressjs.com/)
 - [socket.io](http://socket.io/): this allows us communication between clients and server.
 - [socket.io stream](https://github.com/nkzawa/socket.io-stream): this allows us to stream the file between sender and server.
 
 ### Error handling

 Handling network cutting is a hassle. The most common scenario is the following:
