We have this idea to maintain a log of 'events' or decisions we take in our team. So whenever a new employee joins our team, she/he is able to gain context in a short amount of time by just going through the log.

For starters, we can just maintain a repo and commit these decisions/events to it.

I guess, then, the question is:

1. Is this really needed ? 2. If go ahead with this approach, what are those events or decisions worth committing?

   some examples from the top of my head:
   * we decided to rewrite the auth flow. why? => ...
   * we chose language xyz for this particular module...

We obviously have a wiki that has concrete things like setting up your laptop, information about existing products, blah blah.
