+# Protocol Autogen
+
+This directory contains auto-generated C++ wrapper classes for XRP Ledger protocol types.
+
+## Generated Files
+
+The files in this directory are automatically generated at **CMake configure time** from macro definition files:
+
+- **Transaction classes** (in `transactions/`): Generated from `include/xrpl/protocol/detail/transactions.macro` by `scripts/generate_tx_classes.py`
+- **Ledger entry classes** (in `ledger_entries/`): Generated from `include/xrpl/protocol/detail/ledger_entries.macro` by `scripts/generate_ledger_classes.py`
+
+## Generation Process
+
+The generation happens automatically when you **configure** the project (not during build). When you run CMake, the system:
+
+1. Creates a Python virtual environment in the build directory (`codegen_venv`)
+2. Installs Python dependencies from `scripts/requirements.txt` into the venv (only if needed)
+3. Runs the Python generation scripts using the venv Python interpreter
+4. Parses the macro files to extract type definitions
+5. Generates type-safe C++ wrapper classes using Mako templates
+6. Places the generated headers in this directory
+
+### When Regeneration Happens
+
+The code is regenerated when:
+
+- You run CMake configure for the first time
+- The Python virtual environment doesn't exist
+- `scripts/requirements.txt` has been modified
+
+To force regeneration, delete the build directory and reconfigure.
+
+### Python Dependencies
+
+The code generation requires the following Python packages (automatically installed):
+
+- `pcpp` - C preprocessor for Python
+- `pyparsing` - Parser combinator library
+- `Mako` - Template engine
+
+These are isolated in a virtual environment and won't affect your system Python installation.
+
+## Version Control
+
+The generated `.h` files **are checked into version control**. This means:
+
+- Developers without Python 3 can still build the project using the committed files
+- CI/CD systems don't need to run code generation if files are up to date
+- Changes to generated files are visible in code review
+
+## Modifying Generated Code
+
+**Do not manually edit generated files.** Any changes will be overwritten the next time CMake configure runs.
+
+To modify the generated classes:
+
+- Edit the macro files in `include/xrpl/protocol/detail/`
+- Edit the Mako templates in `scripts/templates/`
+- Edit the generation scripts in `scripts/`
+- Update Python dependencies in `scripts/requirements.txt`
+- Run CMake configure to regenerate
+
+## Adding Common Fields
+
+If you add a new common field to `TxFormats.cpp` or `LedgerFormats.cpp`, you should also update the corresponding base classes and templates manually:
+
+Base classes:
+
+- `TransactionBase.h` - Add getters for new common transaction fields
+- `TransactionBuilderBase.h` - Add setters, and if the field is required, add it to the constructor parameters
+- `LedgerEntryBase.h` - Add getters for new common ledger entry fields
+- `LedgerEntryBuilderBase.h` - Add setters, and if the field is required, add it to the constructor parameters
+
+Templates (update to pass required common fields to base class constructors):
+
+- `scripts/templates/Transaction.h.mako`
+- `scripts/templates/LedgerEntry.h.mako`
+
+These files are **not auto-generated** and must be updated by hand.
