* The multiplayer mode requires Liveblocks API keys (Public and Secret)
* You can get some for free at liveblocks.io
* Be **very careful** though, and keep in mind that by doing so, all your multiplayer rooms data will be stored on livestocks.io SaaS servers, and **NOT** on your server
* Multiplayer mode is completely optional and you don't have to use it
* If API keys are not provided, it will be automatically deactivated
* It could be possible to self-host a multiplayer layer in the future. Some projects have been launched, based on YJS library, such as https://github.com/nimeshnayaju/yjs-tldraw, but sadly none of them is mature enough to be included here.
* Obviously, as soon as multiplayer could be enabled without going through Liveblocks SaaS servers, the app will be updated accordingly
