+Bitcoin Core
+=============
+
+Below are notes on installing Bitcoin Core software on Linux systems.
+
+General Runtime Requirements
+----------------------------
+
+Bitcoin Core requires glibc (GNU C Library) 2.31 or newer.
+
+GUI Runtime Requirements
+------------------------
+
+The GUI executable, `bitcoin-qt`, is based on the Qt 6 framework and uses the `xcb` QPA (Qt Platform Abstraction) platform plugin
+to run on X11. Its runtime library dependencies are as follows:
+- `libfontconfig`
+- `libfreetype`
+
+On Debian, Ubuntu, or their derivatives, you can run the following command to ensure all dependencies are installed:
+```sh
+sudo apt install libfontconfig1 libfreetype6
+```
+
+On Fedora, run:
+```sh
+sudo dnf install fontconfig freetype
+```
+
+For other systems, please consult their documentation.
