Ensure the first heading in PDF documents is marked as Heading Level 1 (H1) for accessibility.

## What this means

In a well-structured PDF, the very first heading should be a Heading 1 (H1), which typically represents the main title or the most important heading in the document. This is similar to the primary heading on a webpage, setting the context for the content that follows.

## Why it matters

1. **Accessibility**: For screen reader users, an H1 heading is the primary entry point to understand what the document is about. It's crucial for navigating and comprehending the content.
2. **Document Structure**: The H1 heading sets the stage for the document's structure, much like a book's title. It helps in organizing the content logically.
3. **Search Engine Optimization**: For documents available online, having a clear H1 heading can aid in search engine recognition and ranking.

## How to fix

1. **Review Your Document**: Open your PDF and check the first heading. It should be marked as H1, clearly indicating the main topic or title of the document.
2. **Edit if Necessary**: If the first heading is not H1, use a PDF editing tool to change the heading level. Ensure that it is prominently styled and stands out as the main title.
3. **Maintain Hierarchy**: After setting the H1, ensure that subsequent headings follow in a logical hierarchical order (H2, H3, etc.).

## Testing Methodology

Silktide's identifies the first heading (if any) and verifies 
if it is correctly marked as H1.

### Limitations
- **Styling vs. Tagging**: Silktide detects headings based on tagging, not styling. A visually prominent heading might not be detected as H1 if not tagged correctly.
- **Document Variations**: In some documents, like research papers, the first heading might not be the main title. Silktide's check assumes standard document formatting.
