# SignalR "Hello World" Sample
2+
3+
## Introduction
4+
5+
This quite small sample can be used to describe the general idea
6+
of [SignalR](http://www.asp.net/signalr). It sets up a self-hosted
7+
OWin server (command line exe) with a server-side SignalR hub
8+
and a simple JavaScript client.
9+
10+
With the client, users can start a game or join an existing game.
11+
Once a user starts a game, it waits for another user to join.
12+
Once a second user joined, both players can start shooting. Each
13+
game has exactly two players.
14+
15+
## NuGet Packages
16+
17+
This samples uses the following NuGet packages:
18+
19+
- `Microsoft.AspNet.SignalR.SelfHost`
20+
- `Microsoft.Owin.Cors`
21+
- `Microsoft.Owin.StaticFiles`
22+
23+
## Components of the Sample
24+
25+
- [Startup.cs](Startup.cs) contains the OWin startup code
26+
- [GameHub.cs](GameHub.cs) contains the server-side SignalR hub
27+
- [index.html](wwwroot/index.html) and [index.js](wwwroot/index.js)
28+
contain the client-side SignalR code
