5 | A little buzzer app for running your own quizzes or game shows! Uses websockets to sent messages.
6 |
7 | ## Running the app
8 |
9 | You'll need [Node.js](https://nodejs.org) or [Docker](https://www.docker.com/) to run this
10 | application. For Node:
11 |
12 | ```
13 | npm install
14 | node index.js
15 | ```
16 |
17 | For Docker:
18 |
19 | ```
20 | docker build -t buzzer .
21 | docker run -p 8090:8090 buzzer
22 | ```
23 |
24 | Open http://localhost:8090 in your browser to start!
25 |
26 | ## How to use
27 |
28 | The players goto the homepage (`http://localhost:8090/`) and they can enter their name and team
29 | number. Joining will give them a giant buzzer button!
30 |
31 | The host heads over to `/host` and will be able to see everyone that buzzes in and clear the list
32 | in between questions.
33 |
34 | Join a team | Buzz in | Host view |
