How to *actually* self-host?

[maltfield]

Is it possible to actually self-host cryptoloot?

The README of this repo is contradictory, specifically these two quotes:

Self Hosted Library for CryptoLoot v3.0
...
Register at https://crypto-loot.org to get your public site ID

Sorry, but the definition of self-hosting is that you do not rely on a remote server.

Is it possible to self-host cryptoloot without needing to register on crypto-loot.org?
