Markdown README Editor

Readme MD Editor is a content-first tool focused on the semantics of Markdown rather than presentation. It enables precise authoring, validation, and conversion workflows for README and project documentation. Users include developers, technical writers, and teams maintaining open source or internal docs who require consistent syntax checks, deterministic exports, and reliable anchor generation for in-document navigation.

Conceptually, the tool parses Markdown into a structured representation, applies a rendering pipeline, and outputs both Markdown text and HTML. The core engine adheres to the CommonMark baseline, with optional GitHub Flavored extensions. It preserves code blocks, tables, and links while escaping HTML when exporting. Diagnostics report syntax and style issues with line/column information, enabling quick correction.

Beneficiaries gain a reliable editing and publishing workflow where documentation aligns with code and is ready for CI pipelines. Unique differentiators include a strict separation between content semantics and presentation, a small, predictable extension surface, and deterministic anchor generation. Use cases include README drafting, changelog updates, and library docs in automated pipelines.

Core features include input text and optional filename, export formats, diagnostic collection, heading anchors, and support for extensions; outputs include Markdown text, HTML, and metadata about headings; error handling covers missing inputs and invalid constructs; localization defaults to UTF-8 and supports multilingual content.
