+History
+-------
+
+The origins of this project trace back to 2015, when an in-house, never-released script called **fpga_tools**, written in *Perl*, was used to populate templates for the Xilinx ISE tool.
+
+In 2016, the project was renamed **fpga_helpers**, transitioning from *Perl* to *Python*.
+It was published as open-source on GitHub, adding support for Xilinx Vivado and Altera Quartus, and later for Microsemi (now Microchip) Libero-SoC.
+It evolved into a Makefile-based system with two Tcl scripts - one for synthesis and another for programming - both designed to support multiple vendors, along with a few automation scripts.
+
+By the end of 2019, **PyFPGA** emerged as a complete rewrite, replacing the Makefile and Tcl scripts with a Python-based workflow system.
+The project was launched on GitLab, with its first official release (0.1.0) on February 29, 2020 - just before the onset of the COVID-19 pandemic.
+
+Throughout 2020, support for open-source tools was gradually introduced.
+Initially, Yosys was integrated as the synthesizer, while ISE/Vivado handled place-and-route and bitstream generation.
+Later, support for VHDL via *ghdl-yosys-plugin* was added, followed by the introduction of OpenFlow - a fully solved with FLOSS tools workflow - at the end of the year.
+Additionally, command-line utilities were introduced to simplify working with small projects and simple and quick proof-of-concepts.
+
+In 2021, PyFPGA was migrated from GitLab to GitHub, aligning with the broader FPGA-related FLOSS ecosystem.
+That year, the codebase was significantly expanded and improved, but it also became more complex to maintain.
+This led to the release of version 0.2.0 on May 15, 2022, marking a new starting point.
+
+Between 2023 and 2024, the project underwent a major rewrite, incorporating substantial improvements.
+In 2024, support for a new vendor tool, Diamond, was contributed.
+As a result, a new release is taking place in March 2025.
