+FlatLaf Linux Native Library
+============================
+
+This sub-project contains the source code for the FlatLaf Linux native library.
+
+The native library can be built only on Linux and requires a C++ compiler.
+
+To be able to build FlatLaf on any platform, and without C++ compiler, the
+pre-built native library is checked into Git at
+[flatlaf-core/src/main/resources/com/formdev/flatlaf/natives/](https://github.com/JFormDesigner/FlatLaf/tree/main/flatlaf-core/src/main/resources/com/formdev/flatlaf/natives).
+
+The native library was built on a GitHub server with the help of GitHub Actions.
+See:
+[Native Libraries](https://github.com/JFormDesigner/FlatLaf/actions/workflows/natives.yml)
+workflow. Then the produced Artifacts ZIP was downloaded and the native library
+checked into Git.
+
+
+## Development
+
+To build the library on Linux, some packages needs to be installed.
+
+
+### Ubuntu
+
+`build-essential` contains GCC and development tools. `libxt-dev` contains the
+X11 toolkit development headers.
+
+~~~
+sudo apt update
+sudo apt install build-essential libxt-dev
+~~~
+
+
+### CentOS
+
+~~~
+sudo yum install libXt-devel
