+
+        # GHDL 5.0.0-dev
+
+        GHDL offers the simulator and synthesis tool for VHDL. GHDL can be build for various backends:
+        * `gcc` - using the GCC compiler framework
+        * `mcode` - in memory code generation
+        * `llvm` - using the LLVM compiler framework
+        * `llvm-jit` - using the LLVM compiler framework, but in memory
+
+        The following asset categories are provided for GHDL:
+        * macOS x64-64 builds as TAR/GZ file
+        * macOS aarch64 builds as TAR/GZ file
+        * Ubuntu 24.04 LTS builds as TAR/GZ file
+        * Windows builds for standalone usage (without MSYS2) as ZIP file
+        * MSYS2 packages as TAR/ZST file
+
+        # pyGHDL 5.0.0-dev
+
+        The Python package `pyGHDL` offers Python binding (`pyGHDL.libghdl`) to a `libghdl` shared library (`*.so`/`*.dll`).
+        In addition to the low-level binding layer, pyGHDL offers:
+        * a Language Server Protocol (LSP) instance for e.g. live code checking by editors
+        * a Code Document Object Model (CodeDOM) based on [pyVHDLModel](https://github.com/VHDL/pyVHDLModel)
+
+        The following asset categories are provided for pyGHDL:
+        * Platform specific Python wheel package for Ubuntu incl. `pyGHDL...so`
+        * Platform specific Python wheel package for Windows incl. `pyGHDL...dll`
