+# Typthon Renaming Guide
+
+This document tracks the ongoing effort to rename Python/Py* prefixes to Typthon/Ty* throughout the codebase.
+
+## Overview
+
+Typthon is a fork of Python that aims to become a strictly typed language. As part of this transformation, we're systematically renaming all Python-related prefixes to Typthon equivalents.
+
+## Completed Renamings
+
+### Phase 1: Core API Functions (Completed in PR #21)
+- Basic Py* → Ty* renames for most of the codebase
+- Core Python API functions
+- Type system functions
+- Object management functions
+
+### Phase 2: Build System Fixes (This PR)
+
+#### Python/crossinterp.c
+- ✅ `PyMem_RawCalloc` → `TyMem_RawCalloc` (7 occurrences)
+- ✅ `PyMem_RawMalloc` → `TyMem_RawMalloc` (2 occurrences)
+- ✅ `PyThreadState_Get` → `TyThreadState_Get` (5 occurrences)
+- ✅ `PyThreadState_Swap` → `TyThreadState_Swap` (8 occurrences)
+- ✅ `PyThreadState_Clear` → `TyThreadState_Clear` (2 occurrences)
+- ✅ `PyThreadState_Delete` → `TyThreadState_Delete` (2 occurrences)
+- ✅ `PyThreadState_GET` → `TyThreadState_GET` (1 occurrence)
+- ✅ `PyThreadState_GetInterpreter` → `TyThreadState_GetInterpreter` (4 occurrences)
+- ✅ `PyInterpreterState_Get` → `TyInterpreterState_Get` (5 occurrences)
+- ✅ `PyInterpreterState_GetID` → `TyInterpreterState_GetID` (3 occurrences)
+- ✅ `PyInterpreterState_GetDict` → `TyInterpreterState_GetDict` (1 occurrence)
+- ✅ `PyInterpreterState_Delete` → `TyInterpreterState_Delete` (1 occurrence)
+- ✅ `PyMarshal_ReadObjectFromString` → `TyMarshal_ReadObjectFromString` (1 occurrence)
+- ✅ `PyMarshal_WriteObjectToString` → `TyMarshal_WriteObjectToString` (1 occurrence)
+
+#### Python/specialize.c
+- ✅ `_Py_OPCODE` → `_Ty_OPCODE` (2 occurrences)
+
+#### Modules/atexitmodule.c
+- ✅ `Py_BEGIN_CRITICAL_SECTION` → `Ty_BEGIN_CRITICAL_SECTION` (1 occurrence)
+- ✅ `Py_END_CRITICAL_SECTION` → `Ty_END_CRITICAL_SECTION` (1 occurrence)
+
+## Remaining Work
+
+### Missing Function Implementations
+
+The following functions are referenced but not yet implemented or need to be found in the codebase:
+
+1. `_Ty_bswap32` - Byte swap function (referenced in unicodeobject.c)
+2. `Ty_off_t_converter` - File offset converter (referenced in posixmodule.c)
+3. Various `_Ty_Specialize_*` functions:
+   - `_Ty_Specialize_BinaryOp`
+   - `_Ty_Specialize_Call`
+   - `_Ty_Specialize_CallKw`
+   - `_Ty_Specialize_CompareOp`
+   - `_Ty_Specialize_ContainsOp`
+   - `_Ty_Specialize_ForIter`
+   - `_Ty_Specialize_LoadAttr`
+   - `_Ty_Specialize_LoadGlobal`
+   - `_Ty_Specialize_LoadSuperAttr`
+   - `_Ty_Specialize_Send`
+   - `_Ty_Specialize_StoreAttr`
+   - `_Ty_Specialize_StoreSubscr`
+   - `_Ty_Specialize_ToBool`
+   - `_Ty_Specialize_UnpackSequence`
+4. `_Ty_InitCleanup` - Cleanup initialization function
+
+### Directory Structure
+
+Per the requirement to rename the Python folder to Typthon, we still need to:
+- [ ] Rename `Python/` directory to `Typthon/`
+- [ ] Update all references in `CMakeLists.txt`
+- [ ] Update all #include paths
+- [ ] Update documentation
+
+## Impact on Strict Typing Goals
+
+The renaming work is a prerequisite for implementing strict typing in Typthon because:
+
+1. **Clear Identity**: Establishes Typthon as distinct from Python
+2. **Clean Foundation**: Ensures all APIs use consistent naming
+3. **Future Extensibility**: Makes it easier to add new typed features without confusion
+4. **Documentation**: Makes it clear what belongs to Typthon vs. Python compatibility layers
+
+## Testing
+
+After each batch of renames, we verify:
+- ✅ Code compiles without syntax errors
+- 🔄 Linker errors are being resolved progressively
+- ⏳ Test suite passes (pending full build)
+- ⏳ Version output works: `typthon --version`
+- ⏳ Help works: `typthon --help`
+
+## Notes
+
+- Some references to "Py" in comments are intentionally left unchanged when they refer to the Python compatibility or origin
+- Build is progressing - most Py→Ty renames in core files are complete
+- Next phase will focus on finding/implementing missing specialized functions
