I wanted to include a bit of rationale as to why I went with Vaultwarden instead of the official Bitwarden Open Source server, along with a note about app combability (this is a full server, providing API and application support; it's not just browser-based). To that end, I also added some clarification for novice users that the server must be externally accessible if they want to connect to it via an app from the outside world.
- Replace installation section with a Getting Started, which helps clarify the activation process.
- Clarify security notes with a new section, also including info about Let's Encrypt.
- Add info about backup recommendations.
