A result of a contract where nobody knows where any of the "critical" code lives, I'm gathering a list of "things" a software shop should track that will be beneficial for code/server organization and onboarding new developers. Trying to get this company

Basic Info a Software Shop needs to Track

Installation Path: [Where is the code installed? E.g. D:\Software\CustomServicePath ]
Database Settings: [Connection string for the databases needed, if any]
Custom Configurations: [What config settings need to be set on the server/environment]
