5559cf1460c98eb6998d99784f27de85f95f14d0 doc: Add packages that provide Qt Wayland plugin for Linux (Hennadii Stepanov) Pull request description: When building on Linux using system packages (without depends) the support of Wayland protocol for modern desktop environments (e.g., GNOME, KDE Plasma) depends on the presence of the installed Qt Wayland plugin which is loaded dynamically at the GUI startup. 1. On Debian/Ubuntu, the [`qtwayland5`](https://packages.ubuntu.com/focal/qtwayland5) package is required (also see this [patch](https://codereview.qt-project.org/c/qt/qtbase/+/231227), and this [doc](https://wiki.debian.org/Wayland#Qt_.28supported_since_5.29)): - with `qtwayland5` installed: ``` $ QT_QPA_PLATFORM="wayland;xcb" ./src/qt/bitcoin-qt -printtoconsole Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome.

Bitcoin Core
Setup
Bitcoin Core is the original Bitcoin client and it builds the backbone of the network. It downloads and, by default, stores the entire history of Bitcoin transactions, which requires a few hundred gigabytes of disk space. Depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more.
To download Bitcoin Core, visit bitcoincore.org.
Running
The following are some helpful notes on how to run Bitcoin Core on your native platform.
Unix
Unpack the files into a directory and run:
bin/bitcoin-qt(GUI) orbin/bitcoind(headless)
Windows
Unpack the files into a directory, and then run bitcoin-qt.exe.
macOS
Drag Bitcoin Core to your applications folder, and then run Bitcoin Core.
