The `Quickstart - Get started in 5 minutes` is so small in the documentiation

Hey. In here: https://github.com/nuz-app/nuz I think the getting started is a main section of each documantation, so i suggest to make it h1 and maybe put it also at top of doc as well. (a big getting started on top, also another one on bottom.) (personally i looked for about 5 minutes and just found it randomly. didn't expect it to be a small heading in the end of documantation.)

At the same time, I will be updated documents for Nuz on the website at https://docs.nuz.app. At done, I will update getting started at h1 and put it at top of readme. Many thanks for this issue and please following the project to updates more information in the future.
