### Packages and Dependencies
For Angular based projects, you can simply run:
```shell
npm install @ionic/angular@v5-lts @ionic/angular-toolkit@4.0.0 --save
```
For React projects, you can run:
```shell
npm install @ionic/react@v5-lts @ionic/react-router@v5-lts ionicons@5.5.3
```
For Stencil / vanilla JS projects, you can run:
```shell
npm i @ionic/core@v5-lts --save
```
If you would like a fresh project starter, a new project base can be created from the CLI and an existing app can be migrated over manually.
