+## Repository Overview
+
+This is the awesome-python repository - a curated list of Python frameworks, libraries, software and resources. The repository serves as a comprehensive directory about Python ecosystem.
+
+## PR Review Guidelines
+
+**For all PR review tasks, refer to [CONTRIBUTING.md](CONTRIBUTING.md)** which contains:
+
+- Acceptance criteria (Industry Standard, Rising Star, Hidden Gem)
+- Quality requirements
+- Automatic rejection criteria
+- Entry format reference
+- PR description template
+
+## Architecture & Structure
+
+The repository follows a single-file architecture:
+
+- **README.md**: All content in hierarchical structure (categories, subcategories, entries)
+- **CONTRIBUTING.md**: Submission guidelines and review criteria
+- **sort.py**: Script to enforce alphabetical ordering
+
+Entry format: `* [project-name](url) - Concise description ending with period.`
+
+## Key Considerations
+
+- This is a curated list, not a code project
+- Quality over quantity - only "awesome" projects
+- Alphabetical ordering within categories is mandatory
+- README.md is the source of truth for all content
