# MarkItDown Converter/Plugin Creation

## Quick Reference

### Converter Interface

```python
from markitdown import DocumentConverter, DocumentConverterResult, StreamInfo

class MyConverter(DocumentConverter):
    ACCEPTED_MIME_TYPE_PREFIXES = ["application/vnd.myformat"]
    ACCEPTED_FILE_EXTENSIONS = [".myf"]

    def accepts(self, file_stream: BinaryIO, stream_info: StreamInfo, **kwargs) -> bool:
        # Check extension first (exact match), then MIME type prefix
        # MUST NOT change stream position — seek back if you read
        extension = (stream_info.extension or "").lower()
        if extension in self.ACCEPTED_FILE_EXTENSIONS:
            return True
        mimetype = (stream_info.mimetype or "").lower()
        return any(mimetype.startswith(p) for p in self.ACCEPTED_MIME_TYPE_PREFIXES)

    def convert(self, file_stream: BinaryIO, stream_info: StreamInfo, **kwargs) -> DocumentConverterResult:
        # Read the stream and produce Markdown
        content = file_stream.read()
        markdown = self._do_conversion(content)
        return DocumentConverterResult(markdown=markdown)
```
