Next JS overall recommendation to start

Summarizing my previous topics, so maybe someone would have some general recomendation abdout how to start? My developers are also involved in the proccess, but their time is not unlimited, and they would like to just set up all, teach me what buttons to click, and then go do their work. Any advice about Next JS would be highly appreciated.

A default file, should be supported out of the box. At least it says that it’s system one. Workflow is the same as usually. Upload file, pre translate, review everythgin, make some corrects, download translation, connect it with your source, and it’s all.
