# Getting Started
## Generate an RSS Feed
To subscribe to a Twitter user's timeline, first look at the route document of [Twitter User Timeline](/routes/social-media#twitter-user-timeline).
`/twitter/user/:id` is the route where `:id` is the actual Twitter username you need to replace. For instance, `/twitter/user/DIYgod` with a prefix domain name will give you the timeline of Twitter user DIYgod.
The demo instance will generate an RSS feed at `https://rsshub.app/twitter/user/DIYgod`, use your own domain name when applicable. This feed should work with all RSS readers conforming to the RSS Standard.
You can replace the domain name `https://rsshub.app` with your [self-hosted instance](/install) or any [public instance](/instances).
RSSHub supports additional parameters such as content filtering and full-text extraction, refer to [Parameters](/parameter) for details.
## Contribute a New Route
Our thriving community is the key to RSSHub's success, we invite everyone to join us and [contribute new routes](/joinus/quick-start) for all kinds of interesting sources.
## Use as a npm Package
Apart from serving as an information source hub, RSSHub is also made compatible with all Node.js projects as an npm Package.

}

## Radar
In addition to the two functions of generating RSS and obtaining data, RSSHub also provides a Radar function, which is used to map website addresses to RSSHub addresses.
### Configuration file
Radar has two types of configuration files, one is a full-featured [js file](https://github.com/DIYgod/RSSHub/blob/gh-pages/build/radar-rules.js), and the other is a simplified [json file]((https://github.com/DIYgod/RSSHub/blob/gh-pages/build/radar-rules.json)).
### Usage
You need to use supported browser extensions, mobile apps, RSS readers, or other tools to use the Radar feature. Please refer to the documentation of the corresponding tool for specific usage instructions.
