1. yarn install
2. If you want to test with a local server, you probably want to install CouchDB: Setup guide.
3. yarn start should start a server running on http://localhost:8080. If you just want to build the project, try npm run build.
   • If you're trying to connect by IP (e.g. to test on your phone) you might need to use yarn start --host 0.0.0.0. Nobody really knows why.

Other targets:

• yarn test — Run automated tests
• yarn start:prod — Test the production version
• yarn build:prod — Just build the production version. For example, to get package size information run: yarn build:prod --profile --json stats.json.
• yarn storybook — Play with components
• yarn build:storybook — Check that storybook still builds
