Execution error (MalformedURLException) at java.net.URL/<init>

Hi
While trying to setup a connection with Salesforce I ran into the following issue:

Execution error (MalformedURLException) at java.net.URL/ (URL.java:672).
no protocol: /services/data/v51.0/sobjects/Account

This is code that I used, and I got a warning and exception while loading it into the REPL

Connecting to local nREPL server...
nREPL server started on port 56447 on host localhost - nrepl://localhost:56447

Any thoughts on how I can resolve this?

Ah, I seem to have found the issue.
I read in the documentation that you can:

"...optionally pass in :login-host if you want to use test.salesforce.com or my.salesforce.com addresses"

So, I added the :login-host to the config map, but after some digging through the source code it seems that you have to use
:sandbox? :IS_SANDBOX instead.

That's correct right?
Should the README.md file then be updated or is this something that should be added to the source code?
