-## Code generation
-
-The protocol wrapper classes in `include/xrpl/protocol_autogen/` are generated
-from macro definition files in `include/xrpl/protocol/detail/`. If you modify
-the macro files (e.g. `transactions.macro`, `ledger_entries.macro`) or the
-generation scripts/templates in `cmake/scripts/codegen/`, you need to regenerate the
-files:
-
-```
-cmake --build . --target setup_code_gen  # create venv and install dependencies (once)
-cmake --build . --target code_gen        # regenerate code
-```
-
-The regenerated files should be committed alongside your changes.
