We'll have to install several packages in order to get everything to work. First, just get the react-native-debugger executable from its releases page at https://github.com/jhen0409/react-native-debugger/releases. Installation is just a matter of unzipping the file you downloaded; execution simply requires running the executable within the unzipped directory.

We'll require a couple of packages in order to connect our app, which be get by running either on a simulator or on an actual device, with react-native-debugger. Let's install these with the following command:

npm install react-devtools remote-redux-devtools --save-dev

We now have everything we need. Let's look at a few details on integrating the tools (mostly, the Redux debugger) with our app, and we'll be ready to start debugging.
