+# Development Container Configuration
+
+This directory contains the configuration for a VS Code development container that provides a complete development environment for the wizard-template project.
+
+## Features
+
+- **Python Versions**: Includes Python 3.10, 3.11, 3.12, 3.13, and 3.14 (managed via pyenv)
+- **Hatch**: Pre-installed project management tool
+- **Pre-configured VS Code**: Extensions and settings optimized for Python development
+- **Pre-commit Hooks**: Automatically installed on container creation
+
+## What's Included
+
+### Tools
+
+- **Hatch**: Python project management tool (installed via pipx)
+- **Pyenv**: Python version management (for managing multiple Python versions)
+- **Git**: Version control
+- **Build tools**: Essential build dependencies for Python packages
+
+### VS Code Extensions
+
+- Python extension with Pylance
+- Ruff linter and formatter
+- Better TOML support
+- GitHub Copilot (if available)
+
+### Configuration
+
+- Python formatting and linting configured for Ruff
+- Format on save enabled
+- Pytest testing framework configured
+- Virtual environments stored in `.venv` directory
+
+## Usage
+
+### Opening in VS Code
+
+1. Install the [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
+2. Open the project in VS Code
+3. When prompted, click "Reopen in Container" (or use Command Palette: "Dev Containers: Reopen in Container")
+4. Wait for the container to build and the post-create script to complete
+
+### First-Time Setup
+
+The post-create script automatically:
+1. Installs pyenv for Python version management
+2. Installs Python versions 3.10, 3.11, 3.12, 3.13, and 3.14
+3. Configures hatch to use local virtual environments
+4. Installs pre-commit hooks
+
+### Working with Multiple Python Versions
+
+All Python versions are available via pyenv:
+
+```bash
+# List all installed Python versions
+pyenv versions
+
+# Use a specific version for the current shell
+pyenv shell 3.11
+
+# Use a specific version for the current directory
+pyenv local 3.11
+
+# Run tests with a specific Python version using hatch
+hatch run +py=3.11 test
+```
+
+### Running Common Tasks
+
+```bash
+# Install dependencies and run tests
+hatch run test
+
+# Run quality assurance checks
+hatch run qa
+
+# Build documentation
+hatch run docs:build
+
+# Run pre-commit hooks
+hatch run check
+```
+
+## Customization
+
+To customize the development container:
+
+1. Edit `devcontainer.json` to add features, extensions, or change settings
+2. Modify `post-create.sh` to change post-creation setup steps
+3. Rebuild the container: Command Palette → "Dev Containers: Rebuild Container"
+
+## Troubleshooting
+
+### Python Version Not Found
+
+If a Python version is not available:
+
+```bash
+# List available versions
+pyenv install --list
+
+# Install a specific version
+pyenv install 3.12.1
+
+# Set it as global
+pyenv global 3.10.x 3.11.x 3.12.1 3.13.x 3.14.x
+```
+
+### Hatch Not Found
+
+If hatch is not available:
+
+```bash
+# Install hatch via pipx
+pipx install hatch
+
+# Or install it via pip
+pip install hatch
+```
+
+## Technical Details
+
+- **Base Image**: `mcr.microsoft.com/devcontainers/python:1-3.12-bookworm`
+- **Default Python**: 3.12 (from base image)
+- **Additional Pythons**: Installed via pyenv
+- **Package Manager**: Hatch with uv installer
+- **User**: `vscode` (non-root)

+
+1. Open the project in VS Code with the [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers) installed.
+
+1. Click "Reopen in Container" when prompted (or use Command Palette: "Dev Containers: Reopen in Container").
+
+1. Wait for the container to build and the post-create script to complete. This will:
+   - Install Hatch
+   - Install Python versions 3.10, 3.11, 3.12, 3.13, and 3.14
+   - Install pre-commit hooks
+   - Configure the development environment
+
+1. Run the renaming script to customize your project:

+1. Verify everything is working:
+
+   ```bash
+   hatch run qa
+   ```
+
+See [`.devcontainer/README.md`](https://github.com/fschuch/wizard-template/blob/main/.devcontainer/README.md) for more details about the dev container configuration.
+
+## Option 2: Manual Setup
+
 1. Create your project by clicking on [Use this template](https://github.com/new?template_name=wizard-template&template_owner=fschuch) to generate a new repository from this template.
