Originally, this library was doing two things: (1) providing shims for ssb libraries to work with react-native, (2) providing a manifest that would be used in the ssb config. These two things are now split out from this library. (1) is
react-native-ssb-shims and (2) should be done in the application repository (e.g. MMMMM and others).
npm install, not Yarn.
npm install --save react-native-ssb-client
