+The top level is fully generated from python code in the `doitcode` subdirectory. pydoit is used to generate the desig with the provided `dodo.py` file in the top directory. The code depends on some external modules that are assumed to be installed:
 
-## Please fill in your project documentation in this README.md file 
+* [PDKMaster](https://gitlab.com/Chips4Makers/PDKMaster): python framework (under heavy development) to ease generation of circuits and corresponding DRC compliant layout. This based on a description of a technology with python souce code to allow easy porting to different technologies.
+* [c4m-flexcell](https://gitlab.com/Chips4Makers/c4m-flexcell): a (currently minimal) standard cell library based on PDKMaster
+* [c4m-flexmem](https://gitlab.com/Chips4Makers/c4m-flexmem): the source for the memory compiler
+* [c4m-pdk-sky130](https://gitlab.com/Chips4Makers/c4m-pdk-sky130): the source for the PDKMaster based PDK for the Sky130 technology.
