Databases

TODO: What a database is and how Profilarr uses it. Covers what a Profilarr Compliant Database (PCD) contains and why Profilarr starts you from a maintained database instead of having you write every profile and custom format yourself, the databases you can link (Dictionarry, TRaSH Guides, Dumpstarr, or your own), the Dictionarry database linked on first start, linking another one with its sync interval and auto-pull settings, checking for and pulling updates, the Updates tab, and unlinking.
