+# Test Lint Rule Levels
+
+This file demonstrates different markdown linting rule levels.
+
+## Error Rules (Will Fail PR)
+
+### MD009 - No Trailing Spaces
+This line has a trailing space: 
+
+### MD012 - No Multiple Blanks
+
+
+This line has multiple blank lines above it.
+
+### MD013 - Line Length
+This is a very long line that exceeds the default line length limit and should trigger an error because it's too long and violates the line length rule.
+
+### MD041 - First Line Heading
+This file starts with an h1 heading, which is correct.
+
+## Warning Rules (Will Show Warning but Pass PR)
+
+### MD025 - Single H1 (Multiple Top-Level Headings)
+This file has one h1 heading at the top, which is correct.
+
+### MD024 - No Duplicate Heading
+## Duplicate Heading
+Some content here.
+## Duplicate Heading
+This duplicate heading should trigger a warning.
+
+### MD026 - No Trailing Punctuation in Heading
+## Heading with trailing punctuation?
+
+## Summary
+
+- **Errors** (fail PR): trailing spaces, multiple blanks, long lines, missing first heading
+- **Warnings** (pass PR): multiple h1s, duplicate headings, trailing punctuation in headings

+# Test Lint Rules
+
+This file contains test cases for various markdown linting rules.
+
+## Test Case 1: Valid - Single H1
+
+This file has exactly one h1 heading (`# Test Lint Rules`) which is valid according to the `no-multiple-h1` rule.
+
+## Test Case 2: Valid - Multiple H2+ Headings
+
+### This is an H3 heading
+
+#### This is an H4 heading
+
+##### This is an H5 heading
+
+Multiple h2-h6 headings are allowed.
+
+## Test Case 3: Invalid Example (Commented Out)
+
+The following would violate the single-h1 rule:
+
+<!-- 
+# First H1 Heading
+
+Some content here.
+
+# Second H1 Heading
+
+This would cause a linting warning because there are multiple h1 headings in the same file.
+-->
+
+## Test Case 4: Valid - Mixed Heading Levels
+
+### Subsection 1
+Content for subsection 1.
+
+### Subsection 2  
+Content for subsection 2.
+
+#### Sub-subsection
+More detailed content.
+
+## Test Case 5: Valid - No Additional H1
+
+This file demonstrates that having exactly one h1 at the top is valid, and all other headings should be h2 or lower.
+
+### Summary
+
+- ✅ One h1 heading at the top
+- ✅ Multiple h2-h6 headings allowed
+- ⚠️ Multiple h1 headings would show as warnings (not errors)
+- ❌ No h1 heading would also fail (if required by other rules)
