+# Markdown Content Rules
+
+The following markdown content rules are enforced in the validators:
+
+1. **Headings**: Use appropriate heading levels (H2, H3, etc.) to structure your content. Do not use an H1 heading, as this will be generated based on the title.
+2. **Lists**: Use bullet points or numbered lists for lists. Ensure proper indentation and spacing.
+3. **Code Blocks**: Use fenced code blocks for code snippets. Specify the language for syntax highlighting.
+4. **Links**: Use proper markdown syntax for links. Ensure that links are valid and accessible.
+5. **Images**: Use proper markdown syntax for images. Include alt text for accessibility.
+6. **Tables**: Use markdown tables for tabular data. Ensure proper formatting and alignment.
+7. **Line Length**: Limit line length to 400 characters for readability.
+8. **Whitespace**: Use appropriate whitespace to separate sections and improve readability.
+9. **Front Matter**: Include YAML front matter at the beginning of the file with required metadata fields.
+
+## Formatting and Structure
+
+Follow these guidelines for formatting and structuring your markdown content:
+
+- **Headings**: Use `##` for H2 and `###` for H3. Ensure that headings are used in a hierarchical manner. Recommend restructuring if content includes H4, and more strongly recommend for H5.
+- **Lists**: Use `-` for bullet points and `1.` for numbered lists. Indent nested lists with two spaces.
+- **Code Blocks**: Use triple backticks (```) to create fenced code blocks. Specify the language after the opening backticks for syntax highlighting (e.g., `csharp`).
+- **Links**: Use `[link text](URL)` for links. Ensure that the link text is descriptive and the URL is valid.
+- **Images**: Use `` for images. Include a brief description of the image in the alt text.
+- **Tables**: Use `|` to create tables. Ensure that columns are properly aligned and headers are included.
+- **Line Length**: Break lines at 80 characters to improve readability. Use soft line breaks for long paragraphs.
+- **Whitespace**: Use blank lines to separate sections and improve readability. Avoid excessive whitespace.
+

+# GitHub Flavored Markdown (GFM)
+
+Apply these rules per the [GFM spec](https://github.github.com/gfm/) when writing or reviewing `.md` files. GFM is a strict superset of CommonMark. GFM spec for reference only. Do not download GFM Spec.
+
+## Preliminaries
+
+- A line ends at a newline (`U+000A`), carriage return (`U+000D`), or end of file. A blank line contains only spaces or tabs.
+- Tabs behave as 4-space tab stops for block structure but are not expanded in content.
+- Replace `U+0000` with the replacement character `U+FFFD`.
+
+## Leaf Blocks
+
+- **Thematic breaks**: 3+ matching `-`, `_`, or `*` characters on a line with 0–3 spaces indent. No other characters on the line. Can interrupt a paragraph.
+- **ATX headings**: 1–6 `#` characters followed by a space or end of line. Optional closing `#` sequence (preceded by a space). 0–3 spaces indent allowed.
+- **Setext headings**: Text underlined with `=` (level 1) or `-` (level 2). Cannot interrupt a paragraph — blank line required after a preceding paragraph.
+- **Indented code blocks**: Lines indented 4+ spaces. Cannot interrupt a paragraph. Content is literal text, not parsed as Markdown.
+- **Fenced code blocks**: Open with 3+ backticks or tildes (do not mix). Closing fence must use same character with at least the same count. Specify language identifier after the opening fence. Content is literal text.
+- **HTML blocks**: Seven types defined by start/end tag conditions. Types 1–6 can interrupt paragraphs; type 7 cannot. Content is passed through as raw HTML.
+ - Type 1: `
