Follow consistent capitalization rules for technical terms, acronyms, and library names throughout your codebase and documentation: 1. **Capitalize standard acronyms**: Use 'URL', 'JSON', 'API', 'HTML', 'CSS', 'Unicode', etc. rather than lowercase versions. 2. **Capitalize product/library names**: Use 'Pydantic', 'Django', 'React', etc. when referring to them as proper nouns in documentation, comments, and string literals. 3. **Preserve lowercase in code contexts**: Keep technical names lowercase when used in import statements, function calls, or paths where they must match the actual implementation: ```python # Correct: import pydantic # lowercase in import statements # In documentation or comments: # Pydantic provides validation for Python data types # capitalized as proper noun ``` This consistency enhances readability, maintains technical accuracy, and provides a more professional appearance in your documentation and user-facing messages.
