There is documentation for developing FCCSW here: https://hep-fcc.github.io/fcc-tutorials/main/index.html
Gaudi development specific chapter is this: https://hep-fcc.github.io/fcc-tutorials/main/developing-fcc-software/WritingAlgorithms.html
When implementing the algorithm into FCCAnalyses I followed the example of jet flavour tagging. The FCC flavour tagging Gaudi implementation can be found here: https://github.com/key4hep/k4MLJetTagger (see presentation here )
