## Storage
## File
To use file storage (the default) change the storage section in `config.js` to something like:
``` json
{
"path": "./data",
"type": "file"
}
```
Where `path` represents where you want the files stored
### Redis
To use redis storage you must install the redis package in npm globall using
`npm install redis --global`
Once you've done that, your config section should look like:
``` json
{
"type": "redis",
"host": "localhost",
"port": 6379,
"db": 2
}
```
All of which are optional except `type` with very logical default values.
