+# GitHub Actions Workflows
+
+This directory contains CI/CD workflows for the sqlite-vec-client project.
+
+## Workflows
+
+### test.yml - Continuous Integration
+Runs on every push and pull request to `main` and `develop` branches.
+
+**What it does:**
+- Tests across Python 3.9-3.13
+- Tests on Ubuntu, Windows, and macOS
+- Runs linting (ruff check)
+- Runs format checking (ruff format)
+- Runs type checking (mypy)
+- Runs test suite with coverage report
+
+### publish.yml - PyPI Publishing
+Runs automatically when a GitHub release is published.
+
+**What it does:**
+- Builds the package
+- Publishes to PyPI using the PYPI_API_TOKEN secret
+
+## Setup Requirements
+
+### For PyPI Publishing
+1. Generate a PyPI API token at [pypi.org](https://pypi.org/manage/account/token/)
+2. Add `PYPI_API_TOKEN` to GitHub repository secrets
+
+## Badge URL
+
+Add this to your README.md:
