    Create Safe app with typescript support using yarn as a package manager.

npx create-react-app sapps_getting_started --typescript
cd sapps_getting_started
yarn add https://github.com/gnosis/safe-apps-sdk
add description and iconPath to manifest.json (see https://github.com/gnosis/safe-apps-sdk)
Setup cors as mentioned in the readme of https://github.com/gnosis/safe-react-apps
Call initSdk with [/.*localhost.*/] - this allows to use your local safe-react instance
Add listeners (see https://github.com/gnosis/safe-apps-sdk)
Install ipfs (https://gist.github.com/MiguelBel/b3b5f711aa8d9362afa5f16e4e972461)
