+The Amaranth project provides an open-source toolchain for developing hardware
+based on synchronous digital logic using the Python programming language, as
+well as evaluation board definitions, a System on Chip toolkit, and more. It
+aims to be easy to learn and use, reduce or eliminate common coding mistakes,
+and simplify the design of complex hardware with reusable components.
+
+The Amaranth toolchain consists of the Amaranth hardware definition language,
+the standard library, the simulator, and the build system, covering all steps of
+a typical FPGA development workflow. At the same time, it does not restrict the
+designer's choice of tools: existing industry-standard (System)Verilog or VHDL
+code can be integrated into an Amaranth-based design flow, or, conversely,
+Amaranth code can be integrated into an existing Verilog-based design flow.
