To be able to mine the coin you will need the Core-CLI from downloads.
Once you have this, start the daemon by opening your terminal and changing to the directory where the daemon is located.
To run the daemon in Linux use ./nibbled
For Windows users you can navigate to the file using file explorer and just double click to launch.
Allow the daemon to synchronize with the network - you will see the below message once complete:
To start mining simply follow the instruction given via the help command.
If you do not already have a wallet & would like to use the CLI version, open a new terminal (keep the daemon running) and locate the file "nibblewallet"
Run the file using ./nibblewallet
Follow the instruction given on-screen
For the full experience of Nibble, you will need the NibbleDesktop GUI.
