 # TinyTorch Development Workflow
 
-## CLI Tool: `tito`
-
-The main development tool is the `tito` CLI. Common commands:
-
-### Module Development
-```bash
-# Sync module: Python source → notebook → package export
-tito sync --module {module_name}
-
-# Test specific module (uses pytest internally)
-tito test --module {module_name}
-
-# Get project info and status
-tito info
-```
-
-### Examples
-```bash
-# Work with setup module
-tito sync --module setup
-tito test --module setup
-
-# Work with tensor module  
-tito sync --module tensor
-tito test --module tensor
-```
-
-## Development Cycle
-
-1. **Edit**: Modify `modules/{module}/{module}_dev.py`
-   - Use `#| export` to mark code for package export
-   - Use `#| hide` for instructor solutions
-   - Follow NBDev educational pattern
-
-2. **Sync**: `tito sync --module {module}`
-   - Converts Python source to Jupyter notebook
-   - Exports marked code to `tinytorch/` package
-   - Updates package structure
-
-3. **Test**: `tito test --module {module}`
-   - Runs module-specific pytest tests from `modules/{module}/tests/`
-   - Uses pytest framework for all test execution
-   - Validates exported package code
-   - Ensures everything works end-to-end
-
-4. **Commit**: Regular commits at good stages
-   - See [Git Workflow Guidelines](mdc:.cursor/rules/git-workflow.mdc) for commit strategies
-   - Commit when reaching good milestones
-   - Clean up experimental files before committing
-
-## Testing Requirements
-
-- **All tests must use pytest** - No manual testing or other frameworks
-- Test files must be named `test_{module}.py` and located in `modules/{module}/tests/`
-- Tests should use pytest classes, fixtures, and assertions
-- CLI tool uses pytest internally: `subprocess.run([sys.executable, "-m", "pytest", test_file, "-v"])`
-
-## File Relationships
-
-```
-modules/{module}/{module}_dev.py  →  modules/{module}/{module}_dev.ipynb
-                                 ↓
-                            tinytorch/core/{component}.py
-                                 ↑
-                    modules/{module}/tests/test_{module}.py (pytest)
-```
-
-## Module Structure
-
-Each module should be self-contained with:
-- `{module}_dev.py` - Main development file (Python source)
-- `{module}_dev.ipynb` - Generated notebook (auto-created)
-- `README.md` - Module documentation
-- `tests/` - Test directory
-  - `test_{module}.py` - Module tests (pytest format)
-
-Students run and pass all pytest tests locally within the module before using nbdev to export code to the tinytorch package and build/test the overall package.
-
-## Git Workflow
-
-For commit strategies and Git best practices, see [Git Workflow Guidelines](mdc:.cursor/rules/git-workflow.mdc).
-
-Key principles:
-- **Incremental commits** for easy reverts
+## CLI Tool: `
 - **Test before committing** to avoid broken commits
 - **Use feature branches** for larger changes
 - **Descriptive commit messages** that explain what changed
