 +
== Getting Started ==
 +
 
 +
The VeriBlock GUI Wallet requires a local NodeCore instance, or access to a remote one. It also requires Java13+ (oracle/openjdk/adoptOpenJDK).
 +
 
 +
For more information about NodeCore, visit: [[NodeCore QuickStart]] or [[HowTo run NodeCore]].
 +
 
 +
== Screens ==
 +
 
 +
This is a general overview of each screen, highlighting useful features. This section indicates what each screen does.

 +
=== Send ===
 +
 
 +
[[File:GUI_Send_1.jpeg|400px]]
 +
 
 +
[[File:GUI_Send_2.jpeg|400px]]
 +
 
 +
The Send page is used to send VeriBlock coins and to connect or check the status of the GUI Wallet's NodeCore.
 +
 
 +
If the wallet is not connected to NodeCore, the Send page will display "Please connect to NodeCore."
 +
 
 +
Three options will be featured:
 +
:1. Start NodeCore
 +
:: If NodeCore is already on your machine and you want to start it.
 +
:2. Install NodeCore
 +
:: To open a webpage with install instructions.
 +
:3. Reconnect to NodeCore
 +
:: If NodeCore is already running, but you need to reconnect.
 +
 
 +
A link will also be featured on the page to connect to the VeriBlock Discord community for further questions.
 +
 
 +
Once your GUI Wallet is connected to NodeCore, the Send page will be used strictly for sending coins. Multiple address will be listed in the drop-down box located beside "Send From Address" for the user to select when sending VeriBlock coins.
 +
 
 +
This page also features a NodeCore informative bar located at the bottom of the screen. The bar will display whether the GUI Wallet is connected to NodeCore, syncing to NodeCore or not connected to NodeCore. If the GUI Wallet is syncing, this bar will also display an approximate time for the wallet to be fully synced with NodeCore. If the wallet is not connected to NodeCore, the sending transactions options will note appear on the page.
 +
