Before we can create our React app, we need to set the project directory and install the dependencies for our app:

1. Create a new React app called DocsApp using npx: 

npx create-react-app DocsApp

2. Update your package.json to the file so that it has following values:

{
 "name": "DocsApp",
 "version": "1.0.0",
 "private": false,
 "dependencies": {
 "bulma-start": "0.0.2",
 "react": "^16.4.1",
 "react-dom": "^16.4.1",
 "react-scripts": "1.1.4"
 },
 "scripts": {
 "start": "react-scripts start",
 "build": "react-scripts build",
 "test": "react-scripts test --env=jsdom",
 "eject": "react-scripts eject"
 }
}

3. Runnpm install on a Terminal window to install the dependencies.
4. Next, within the src folder, create a Components folder for the app components.

Let's go through the components one by one.
