Current Limitation

It's unclear what needs a moralis server and what is a react-moralis hook. I think clarifying this would be really helpful.

Feature / Enhancement Description

Have the docs have a need initialized or something.

[ErnoW]

Good suggestion.
The code is mostly optimized for an app that is initialised (only recently we added the feature to opt-out, and do initialisation manually). So there are probably quire a few functions that require a connection to moralis-server.

For us, this is a currently low-priority issue, but anyone is open to submit a PR to update the documentation :)
