## Getting Started
### Installation Recap
We install the library and then add the relevant browser dependencies in the index.html file.
```sh
npm install --save @appbaseio/reactivemaps
```
```html
```
You can read more about the installation steps [here](v1.0.0/getting-started/Installation.html).
### Creating an App
Now that we have gotten the installation part out of the way, let's create an app with reactivemaps.
If you already have a React boilerplate setup, then let's go ahead and import the components.
```javascript
import {
ReactiveMap,
SingleList,
ReactiveBase
} from '@appbaseio/reactivemaps';
```
Next, we create a `ReactiveBase` component, which requires creating an [appbase.io](https://appbase.io) app along with `username:password` credentials. This quick GIF will help with creating an app and getting the credentials.
{% raw %}
```
class HelloWorld extends Component {
render() {
return(
)
}
}
```
{% endraw %}
We create a `SingleList` component with New York city selected by default and add a `ReactiveMap` component which updates reactively every time the SingleList component's selected value changes.
If you followed along, you should see something like this:
