+> MarkItDown 0.0.2 alpha 1 (0.0.2a1) introduces a plugin-based architecture. As much as was possible, command-line and Python interfaces have remained the same as 0.0.1a3 to support backward compatibility. Please report any issues you encounter. Some interface changes may yet occur as we continue to refine MarkItDown to a first non-alpha release.

+# MarkItDown Sample Plugin
+
+[![PyPI](https://img.shields.io/pypi/v/markitdown.svg)](https://pypi.org/project/markitdown/)
+![PyPI - Downloads](https://img.shields.io/pypi/dd/markitdown)
+[![Built by AutoGen Team](https://img.shields.io/badge/Built%20by-AutoGen%20Team-blue)](https://github.com/microsoft/autogen)
+
+
+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)
+```

+    """Converts ZIP files to markdown by extracting and converting all contained files.
+
+    The converter extracts the ZIP contents to a temporary directory, processes each file
+    using appropriate converters based on file extensions, and then combines the results
+    into a single markdown document. The temporary directory is cleaned up after processing.
+
+    Example output format:
+    ```markdown
+    Content from the zip file `example.zip`:
+
+    ## File: docs/readme.txt
+
+    This is the content of readme.txt
+    Multiple lines are preserved
+
+    ## File: images/example.jpg
+

+    | data1   | data2   | data3   |

+    ```
+
+    Key features:
+    - Maintains original file structure in headings

+    - Preserves formatting of converted content
+    - Cleans up temporary files after processing
