 For example, if you were previously using the gelf appender (`type: 'gelf'`) then you should add `@log4js-node/gelf` to your dependencies and change the type to `type: '@log4js-node/gelf'`.

-# Redis Appender
-
-Stores log events in a [Redis](https://redis.io) database. You will need to include the [redis](https://www.npmjs.com/package/redis) package in your application's dependencies to use this appender.
-
-## Configuration
-
-* `type` - `redis`
-* `host` - `string` (optional, defaults to `127.0.0.1`) - the location of the redis server
-* `port` - `integer` (optional, defaults to `6379`) - the port the redis server is listening on
-* `pass` - `string` (optional) - password to use when authenticating connection to redis
-* `channel` - `string` - the redis channel that log events will be published to
-* `layout` - `object` (optional, defaults to `messagePassThroughLayout`) - the layout to use for log events (see [layouts](layouts.md)).
-
-The appender will use the Redis PUBLISH command to send the log event messages to the channel.
-
-## Example
-
-```javascript
-log4js.configure({
-  appenders: {
-    redis: { type: 'redis', channel: 'logs' }
-  },
-  categories: { default: { appenders: ['redis'], level: 'info' } }
-});
-```
-
-This configuration will publish log messages to the `logs` channel on `127.0.0.1:6379`.
