+# SymPy Project Overview
+
+## Purpose
+SymPy is a Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible to be comprehensible and easily extensible. SymPy is written entirely in Python and depends on mpmath as an external library.
+
+## Technology Stack
+- **Language**: Python (supports Python 2.7 and 3.4+)
+- **Main Dependencies**: 
+  - mpmath (version >= 0.19) - required for mathematical computations
+  - Optional dependencies for specific features (plotting, etc.)
+- **Build System**: setuptools/distutils based setup.py
+- **Testing**: Custom test framework (bin/test) with pytest-like interface
+
+## Key Features
+- Pure Python implementation
+- Symbolic computation capabilities
+- Mathematical functions, algebra, calculus, geometry
+- Code generation capabilities
+- Extensive test suite
+- Cross-platform compatibility

+# Task Completion Guidelines for SymPy
+
+## When a Development Task is Completed
+
+### 1. Testing
+**Always run tests after making changes:**
+- `python bin/test [affected_module]` - Test the specific module you modified
+- `python bin/test` - Run full test suite for comprehensive changes
+- `python bin/doctest [module]` - Test documentation examples if you modified docstrings
+
+### 2. Code Quality Checks
+- `python setup.py audit` - Run pyflakes to check for code issues
+- Manually review code for style compliance with project conventions
+
+### 3. Documentation Updates
+- Update docstrings if you added/modified public APIs
+- Add examples to docstrings when appropriate
+- Update relevant documentation files if needed
+
+### 4. Validation Steps
+- Verify your changes work in the interactive console: `python bin/isympy`
+- Test with different Python versions if making significant changes
+- Check that imports still work correctly
+
+### 5. Performance Considerations
+- For performance-critical changes, consider running benchmarks: `python setup.py bench`
+- Profile code if making changes to core modules
+
+### 6. Integration Testing
+- Test how your changes interact with other SymPy modules
+- Verify backward compatibility is maintained
+- Check that mathematical properties still hold
+
+## Before Submitting Changes
+- Ensure all tests pass
+- Code follows project style guidelines
+- Documentation is updated appropriately
+- Changes are well-tested with edge cases

+- `mkdir dirname` - Create directory
+- `cd dirname` - Change directory
+- `cd ..` - Go up one directory
+- `cd \` - Go to root directory

+
+## Network
+- `ping hostname` - Test network connectivity
+- `ipconfig` - Display network configuration
+
+## Git Commands (same on Windows)
+- All git commands work the same way on Windows

+
+## PowerShell Alternatives
+If using PowerShell instead of Command Prompt:
+- `Get-ChildItem` or `ls` - List directory contents
+- `Get-Content filename` or `cat filename` - Display file contents
+- `Copy-Item` or `cp` - Copy files
+- `Remove-Item` or `rm` - Delete files
