Fresh install of node and arrpc gives module not found 'ws'

[fritz-fritz]

Just wanted to add that the README could use a little tip.

After installing node, cloning the repo, etc... I got the following output.

$ node src   
node:internal/process/esm_loader:40
      internalBinding('errors').triggerUncaughtException(
                                ^

Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'ws' imported from /home/fritz-fritz/git/arrpc/src/bridge.js
Did you mean to import ws/index.js?

}

Node.js v18.19.1

This is fixed by running npm install ws before running node src. This might be obvious to many, but would improve user experience to be documented.
