-> Breaking changes between 0.0.1 to 0.0.2:
-> * Dependencies are now organized into optional feature-groups (further details below). Use `pip install markitdown[all]` to have backward-compatible behavior. 
-> * The DocumentConverter class interface has changed to read from file-like streams rather than file paths. *No temporary files are created anymore*. If you are the maintainer of a plugin, or custom DocumentConverter, you likely need to update your code. Otherwise, if only using the MarkItDown class or CLI (as in these examples), you should not need to change anything.

-MarkItDown is a lightweight Python utility for converting various files to Markdown for use with LLMs and related text analysis pipelines. To this end, it is most comparable to [textract](https://github.com/deanmalmgren/textract), but with a focus on preserving important document structure and content as Markdown (including: headings, lists, tables, links, etc.) While the output is often reasonably presentable and human-friendly, it is meant to be consumed by text analysis tools -- and may not be the best option for high-fidelity document conversions for human consumption.

-At present, MarkItDown supports:
+> 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.

-## Why Markdown?
-
-Markdown is extremely close to plain text, with minimal markup or formatting, but still
-provides a way to represent important document structure. Mainstream LLMs, such as
-OpenAI's GPT-4o, natively "_speak_" Markdown, and often incorporate Markdown into their
-responses unprompted. This suggests that they have been trained on vast amounts of
-Markdown-formatted text, and understand it well. As a side benefit, Markdown conventions
-are also highly token-efficient.

-### Optional Dependencies
-MarkItDown has optional dependencies for activating various file formats. Earlier in this document, we installed all optional dependencies with the `[all]` option. However, you can also install them individually for more control. For example:
-
-```bash
-pip install markitdown[pdf, docx, pptx]
-```
-
-will install only the dependencies for PDF, DOCX, and PPTX files.
-
-At the moment, the following optional dependencies are available:
-
-* `[all]` Installs all optional dependencies
-* `[pptx]` Installs dependencies for PowerPoint files
-* `[docx]` Installs dependencies for Word files
-* `[xlsx]` Installs dependencies for Excel files
-* `[xls]` Installs dependencies for older Excel files
-* `[pdf]` Installs dependencies for PDF files
-* `[outlook]` Installs dependencies for Outlook messages

-* `[audio-transcription]` Installs dependencies for audio transcription of wav and mp3 files
-* `[youtube-transcription]` Installs dependencies for fetching YouTube video transcription

-        IMPORTANT: In rare cases, (e.g., OutlookMsgConverter) we need to read more from the stream to make a final

-        MUST be reset it MUST be reset before returning. This is because the convert() method may be called immediately
-        after accepts(), and will expect the file_stream to be at the original position.
-
-        E.g.,
-        cur_pos = file_stream.tell() # Save the current position
-        data = file_stream.read(100) # ... peek at the first 100 bytes, etc.
-        file_stream.seek(cur_pos)    # Reset the position to the original position

-        - kwargs: Additional keyword arguments for the converter.
