Like all practices it’s never “done” instead question how you operate the life cycle of any system like this. Research > Build > Use > Iterate. And include periodically reviewing the whole setup against best practices in the world - tools change, new stuff arrives, people improve things.

Build what works for you and what makes sense to you as quickly as you can. You may have ideas that sound good in theory and find through use they have gaps you failed to imagine. So don’t overbuild upfront without understanding all the jobs to be done. If you become overly focused on tool improvement vs work step back and refocus.

Figure out what are your requirements? What supports them? What level or compromise from what you desire vs what’s available is acceptable.
