Thank you, I was already reading that guide, but I was a bit confused about that conf file with those lindasilva credentials,
and fctwallet linked to fctwallet.dat, and not to factoid_wallet_bolt.db
So I thought its outdated.
And I thought, that I can set-up my own rpcuser, pass and wallet.
We don't have a "QT style" wallet yet. However as development progresses there will be updates and new wallet apps.
