How to test

If manual testing is required, what are the steps?

Text is good.

I would adjust the Model Mapping and Data Fetching for a smoother flow.

I would love to have in every section some code sample in pseudo typescript. I have drafted some, so try to apply this.

There is already one section about deployment

• rut lint on readme

I have merged data fetching and content modelling into one section, however it seemed to me better to have only one code block there, as it does not make much sense to showcase how the interface looks like. On the other hand as you said people mostly find the the code and then read the lines above... Should I somehow add some generic interface for type there?

From other changes, I made some paragraphs shorter, as I felt that some information were unnecessary. I removed some links, because I thought that it may annoy people more, when there is a lot of links to other files. Also I run prettier on the file. And lastly I have added code blocks for more paragraphs. For instance for Handling 404 I did not add any, it only explain concept what we did, not what developer can do in the project.

For further reference - the best form for readme is to use passive. If you are up for it - you can rewrite the text in this form, but let's keep it optional - for important parts - I have placed the suggestions.

Before sending to another review - run the text using Grammarly.
