Summary and manual testing

Let's summarize what we've accomplished so far:

1. A decentralized app was created using Rell and Chromia.
2. Unit tests were written and a test node was started.
3. The React app was connected to the dapp using the FT client wrapper.

Start the frontend app

To view the changes in our frontend app, start it with this command:

npm run dev

The dapp can now be interacted with. Followers can be added or removed, posts can be created, and content updates can be observed on the feed page.

Congratulations! A first dapp on Chromia has been built and tested successfully.
