1. Create a custom theme class that inherits from pygments.style.Style:

```python
from pygments.style import Style
from pygments.token import Comment, Keyword, Name, Number, Operator, String, Text

class MyCustomTheme(Style):
    background_color = "#1e1e2e"
    highlight_color = "#313244"
    
    styles = {
        Text: "#cdd6f4",
        Comment: "#6c7086",
        Keyword: "#cba6f7",
        Name.Function: "#89b4fa",
        Name.Variable: "#f5c2e7",
        Number: "#fab387",
        Operator: "#94e2d5",
        String: "#a6e3a1",
    }
```

2. Register your theme with Pygments:

```python
from pygments.styles import STYLE_MAP
STYLE_MAP["my-theme"] = "module_name.MyCustomTheme"
```

3. Use your custom theme with Edison:

```python
# In your code
from edison.utils.markdown_utils import print_command_rich
print_command_rich("ls -la", theme="my-theme")

# Or via command line
edison --theme my-theme "list files"
```

4. To make your theme permanently available, create a Python package and install it:

```python
# setup.py
from setuptools import setup

setup(
    name="edison-custom-themes",
    version="0.1.0",
    py_modules=["edison_themes"],
    entry_points={
        "pygments.styles": [
            "my-theme = edison_themes:MyCustomTheme",
        ],
    },
)
```

Then install with: pip install -e .
    """)

if __name__ == "__main__":
    main()
