# MD044 - Use Proper Capitalization for Names
Aliases: `proper-names`
## What this rule does
Ensures brand names, product names, and technical terms are consistently capitalized throughout your documents.
## Why this matters
- **Professional appearance**: Incorrect capitalization looks careless and unprofessional
- **Brand respect**: Shows you care about getting company and product names right
- **Consistency**: Readers won't be confused by different variations of the same name
- **Searchability**: Consistent naming improves search results and indexing
## Examples
### ✅ Correct
With configured names:
```toml
[MD044]
names = ["JavaScript", "GitHub", "Node.js", "TypeScript"]
```
```markdown
# JavaScript Development Guide
This guide covers JavaScript best practices for GitHub projects.
We'll be using Node.js and TypeScript for our examples.
```
### ❌ Incorrect
```markdown
# Javascript Development Guide <!-- Should be "JavaScript" -->
This guide covers javascript best practices for github projects.
We'll be using NodeJS and typescript for our examples.
```
### 🔧 Fixed
```markdown
# JavaScript Development Guide
This guide covers JavaScript best practices for GitHub projects.
We'll be using Node.js and TypeScript for our examples.
```
## Configuration
```toml
[MD044]
names = [] # List of properly capitalized names
code-blocks = false # Check inside code blocks (default: false)
html-elements = true # Check inside HTML elements (default: true)
html-comments = true # Check inside HTML comments (default: true)
```
## Automatic fixes
When enabled, this rule will:
- Replace all incorrect capitalizations with the proper version
- Preserve the context and meaning of your text
- Work across headings, paragraphs, and lists
## Special cases
- Only checks names you've configured
- Won't check inside URLs or file paths
- By default, skips code blocks (set `code-blocks: true` to check them)
- Set `html-comments: false` to skip HTML comment content
- Some names are intentionally lowercase (like "npm")
