First get an idea on a darktable workflow - darktable is not Adobe lightroom.
There’s a wip documentation, but already very useful: https://elstoc.github.io/dtdocs/overview/workflow/
Even for a beginner with darktable i recommend the display-referred workflow. If enabled it gives decent initial results, which can be improved with just a few modules.
quite old but still valid: https://discuss.pixls.us/t/darktable-3-0-for-dummies-in-3-modules
(But this is off topic in this thread)
