# Getting started

{% hint style="info" %}
If you upgraded your project using the [Webapp Rocket Generator](https://github.com/osstotalsoft/generator-webapp-rocket) you can skip to step 2.
{% endhint %}

1. Install `@totalsoft/rocket-ui` package and the following packages must be uninstalled:

* `@totalsoft_oss/rocket-ui.core` 
* `@totalsoft_oss/rocket-ui.themes`

or 

* `@bit/totalsoft_oss.react-mui.kit.core`

2. For each component that was imported from one of the following libraries: `@totalsoft_oss/rocket-ui.core` or  `@bit/totalsoft_oss.react-mui.kit.core` the import must be changed to:

{% code overflow="wrap" lineNumbers="true" %}

```javascript
//old way
import { IconButton } from '@totalsoft_oss/rocket-ui.core'
//new way
import { IconButton } from '@totalsoft/rocket-ui'
```

{% endcode %}

The themes can also be imported from `@totalsoft/rocket-ui`, there are no more different packages:

```javascript
import { defaultTheme } from '@totalsoft/rocket-ui'
```
