This project shows how to create a sample plugin for MarkItDown. The most important parts are as follows:

Next, implement your custom DocumentConverter:

```python
from typing import Union
from markitdown import DocumentConverter, DocumentConverterResult

class RtfConverter(DocumentConverter):
    def convert(self, local_path, **kwargs) -> Union[None, DocumentConverterResult]:
        # Bail if not an RTF file 
        extension = kwargs.get("file_extension", "")
        if extension.lower() != ".rtf":
            return None

	# Implement the conversion logic here ...

        # Return the result
        return DocumentConverterResult(
            title=title,
            text_content=text_content,
        )
```

Next, make sure your package implements and exports the following:

```python
# The version of the plugin interface that this plugin uses. 
# The only supported version is 1 for now.
__plugin_interface_version__ = 1 

# The main entrypoint for the plugin. This is called each time MarkItDown instances are created.
def register_converters(markitdown: MarkItDown, **kwargs):
    """
    Called during construction of MarkItDown instances to register converters provided by plugins.
    """

    # Simply create and attach an RtfConverter instance
    markitdown.register_converter(RtfConverter())
```


Finally, create an entrypoint in the `pyproject.toml` file:

```toml
[project.entry-points."markitdown.plugin"]
sample_plugin = "markitdown_sample_plugin"
```

Here, the value of `sample_plugin` can be any key, but should ideally be the name of the plugin. The value is the fully qualified name of the package implementing the plugin.


## Installation

To use the plugin with MarkItDown, it must be installed. To install the plugin from the current directory use:

```bash
pip install -e .
```

Once the plugin package is installed, verify that it is available to MarkItDown by running:

```bash
markitdown --list-plugins
```

To use the plugin for a conversion use the `--use-plugins` flag. For example, to convert a PDF:

```bash
markitdown --use-plugins path-to-file.pdf
```

In Python, plugins can be enabled as follows:

```python
from markitdown import MarkItDown

md = MarkItDown(enable_plugins=True) 
result = md.convert("path-to-file.pdf")
print(result.text_content)
```
