+# Release Guide
+
+## One-line Release 🚀
+
+```bash
+./scripts/release.sh 0.1.1
+```
+
+That's it! This script will:
+1. Update all package versions
+2. Commit and push changes
+3. Create GitHub release
+4. CI automatically builds and publishes to PyPI
+
+## Manual Testing Before Release
+
+For testing specific packages locally (especially DiskANN on macOS):
+
+```bash
+# Build specific package locally
+./scripts/build_and_test.sh diskann  # or hnsw, core, meta, all
+
+# Test installation in a clean environment
+python -m venv test_env
+source test_env/bin/activate
+pip install packages/*/dist/*.whl
+
+# Upload to Test PyPI (optional)
+./scripts/upload_to_pypi.sh test
+
+# Upload to Production PyPI (use with caution)
+./scripts/upload_to_pypi.sh prod
+```
+
+### Why Manual Build for DiskANN?
+
+DiskANN's complex dependencies (protobuf, abseil, etc.) sometimes require local testing before release. The build script will:
+- Compile the C++ extension
+- Use `delocate` (macOS) or `auditwheel` (Linux) to bundle system libraries
+- Create a self-contained wheel with no external dependencies
+
+## First-time setup
+
+1. Install GitHub CLI:
+   ```bash
+   brew install gh
+   gh auth login
+   ```
+
+2. Set PyPI token in GitHub:
+   ```bash
+   gh secret set PYPI_API_TOKEN
+   # Paste your PyPI token when prompted
+   ```

+# LEANN - The smallest vector index in the world
+
+LEANN is a revolutionary vector database that democratizes personal AI. Transform your laptop into a powerful RAG system that can index and search through millions of documents while using **97% less storage** than traditional solutions **without accuracy loss**.
+
+## Installation
+
+```bash
+# Default installation (HNSW backend, recommended)
+uv pip install leann
+
+# With DiskANN backend (for large-scale deployments)
+uv pip install leann[diskann]
+```
+
+## Quick Start
+
+```python
+from leann import LeannBuilder, LeannSearcher, LeannChat
+
+# Build an index
+builder = LeannBuilder(backend_name="hnsw")
+builder.add_text("LEANN saves 97% storage compared to traditional vector databases.")
+builder.build_index("my_index.leann")
+
+# Search
+searcher = LeannSearcher("my_index.leann")
+results = searcher.search("storage savings", top_k=3)
+
+# Chat with your data
+chat = LeannChat("my_index.leann", llm_config={"type": "ollama", "model": "llama3.2:1b"})
+response = chat.ask("How much storage does LEANN save?")
+```
