NervaOne Guide
NervaOne is the current Nerva GUI, and it now has a guide of its own. The contents of this page have been merged into the GUI Guide, which covers the application in full: installation on desktop and Android, the full node, pruned and wallet-only modes, mining, wallets and transfers, the address book, running a public node, and troubleshooting.
