-Example data analysis project
+Welcome to the Data Analysis Project Structure Guide! This guide is designed to
+help new students understand how to structure data analysis projects in Python
+effectively. By following these best practices, you'll create projects that are
+organized, maintainable, and reproducible.

+## Project Structure
+
+A well-organized project structure is crucial for collaboration and
+scalability. Here's a recommended directory layout:
+
+```
+project-name/
+├── data/
+│   ├── model_weights/          # Trained model weights
+│   ├── raw/                    # Original, unmodified datasets
+│   └── processed/              # Cleaned or transformed data
+├── code/
+│   └── my_python_program.py    # Python scripts
+├── figures/
+├── docs/
+│   ├── my_fancy_latex_thesis/  # LaTeX files for thesis (advised)
+│   ├── my_presentation.pptx    # Presentation slides
+│   └── my_thesis.docx          # Word document (not recommended)
+├── .gitignore                  # Files and directories for Git to ignore
+├── README.md                   # Project overview and instructions
+└── requirements.txt            # Python dependencies
+```
+
+### Separating Data and Code
+
+- **Data Directory (`data/`)**: Store all your datasets here.
+  - `raw/`: Original, unmodified datasets.
+  - `processed/`: Data that's been cleaned or transformed.
+- **Source Code Directory (`code/`)**: Contains all the code scripts and modules.
+
+**Benefits:**
+
+- **Organization**: Keeps your data separate from code, making it easier to manage.
+- **Reproducibility**: Clear separation ensures that data processing steps are documented and repeatable.
+- **Collaboration**: We/you/collaborators can easily find and understand different components of the project.
+
+### Separating Figures and Code
+
+- **Figures Directory (`figures/`)**: Store all generated plots, images, and visualizations.
+
+**Benefits:**
+
+- **Clarity**: Separates output from code, reducing clutter.
+- **Version Control**: Easier to track changes in code without large binary files like images.
+- **Presentation**: Simplifies the process of creating reports or presentations by having all figures in one place.
+
+---
+
+## Version Control with Git
+
+Git is a powerful version control system that helps you track changes,
+collaborate with others, and manage your project's history. But what is version
+control? Have you ever found yourself creating files like `project_final_v2.py`
+or `project_final_final.py`? Version control solves this problem by keeping
+track of changes and allowing you to revert to previous versions.
+As a bonus, you'll also have a backup of your project in case something goes wrong.
+
+### Basic Git Commands
+
+- **Initialize a Repository**
+
+  ```bash
+  git init
+  ```
+
+- **Add Remote Repository (GitHub, Gittea)**
+
+  ```bash
+  git remote add origin <repository-url>
+  ```
+
+- **Clone a Repository**
+
+  ```bash
+  git clone <repository-url>
+  ```
+
+- **Check Status**
+
+  ```bash
+  git status
+  ```
+
+- **Add Changes**
+
+  ```bash
+  git add <file-name>
+  # Or add all changes
+  git add .
+  ```
+
+- **Commit Changes**
+
+  ```bash
+  git commit -m "Commit message"
+  ```
+
+- **Push to Remote Repository**
+
+  ```bash
+  git push origin main
+  ```
+
+- **Pull from Remote Repository**
+
+  ```bash
+  git pull origin main
+  ```
+  #### Advanced Git Commands
+
+- **Create a New Branch**
+
+  ```bash
+  git branch <branch-name>
+  ```
+
+- **Switch Branches**
+
+  ```bash
+  git checkout <branch-name>
+  ```
+
+- **Merge Branches**
+
+  ```bash
+  git merge <branch-name>
+  ```
+
+- **View Commit History**
+
+  ```bash
+  git log
+  ```
+
+**Tips:**
+
+- **Commit Often**: Regular commits make it easier to track changes.
+- **Meaningful Messages**: Use descriptive commit messages for better understanding.
+- **Use `.gitignore`**: Exclude files and directories that shouldn't be tracked (e.g., large data files, virtual environments).

+
+## Best Practices for Data Analysis Projects
+
+1. **Use Virtual Environments**
+
+   - Utilize `venv`, `conda` or `pyenv` to manage project-specific dependencies.
+   - Document dependencies in `requirements.txt` or use `poetry` for package management.
+
+2. **Document Your Work**
+
+   - Maintain a clear and informative `README.md`.
+   - Use docstrings and comments in your code.
+   - Keep a changelog for significant updates.
+
+3. **Write Modular Code**
+
+   - Break code into functions and classes.
+   - Reuse code to avoid duplication.
+
+4. **Follow Coding Standards**
+
+   - Adhere to PEP 8 guidelines for Python code.
+   - Use linters like `flake8` or formatters like `black` or `ruff` to maintain code quality.
+
+5. **Automate Data Processing**
+
+   - Write scripts to automate data cleaning and preprocessing.
+   - Ensure scripts can be run end-to-end to reproduce results.
+
+6. **Test Your Code**
+
+   - Implement unit tests using frameworks like `unittest` or `pytest`.
+   - Keep tests in the `tests/` directory.
+
+7. **Handle Data Carefully**
+
+   - Do not commit data to version control.
+
+8. **Version Your Data and Models**
+
+   - Save model versions with timestamps or unique identifiers.
+
+9. **Backup Regularly**
+
+   - Push changes to a remote repository frequently.
+   - Consider additional backups for critical data.
+
+10. **Collaborate Effectively**
+
+    - Use branches for new features or experiments.
+    - Merge changes with pull requests and code reviews.

+## Conclusion
+
+Structuring your data analysis projects effectively is the first step towards
+successful and reproducible research. By separating data, code, and figures,
+using version control, and following best practices, you set a strong
+foundation for your work and collaboration with others.
+
+Happy coding!
