-# Manylinux Build Strategy
-
-## Problem
-Google Colab requires wheels compatible with `manylinux_2_35_x86_64` or earlier. Our previous builds were producing `manylinux_2_39_x86_64` wheels, which are incompatible.
-
-## Solution
-We're using `cibuildwheel` with `manylinux_2_35` images to build wheels that are compatible with Google Colab while maintaining modern toolchain features.
-
-### Key Changes
-
-1. **cibuildwheel Configuration**
-   - Using `manylinux2014` images (provides `manylinux_2_17` compatibility)
-   - Using `yum` package manager (CentOS 7 based)
-   - Installing `cmake3` and creating symlink for compatibility
-
-2. **Build Matrix**
-   - Python versions: 3.9, 3.10, 3.11, 3.12, 3.13
-   - Platforms: Linux (x86_64), macOS
-   - No Windows support (not required)
-
-3. **Dependencies**
-   - Linux: gcc-c++, boost-devel, zeromq-devel, openblas-devel, cmake3
-   - macOS: boost, zeromq, openblas, cmake (via Homebrew)
-
-4. **Environment Variables**
-   - `CMAKE_BUILD_PARALLEL_LEVEL=8`: Speed up builds
-   - `Python_FIND_VIRTUALENV=ONLY`: Help CMake find Python in cibuildwheel env
-   - `Python3_FIND_VIRTUALENV=ONLY`: Alternative variable for compatibility
-
-## Testing Strategy
-
-1. **CI Pipeline**: `test-manylinux.yml`
-   - Triggers on PR to main, manual dispatch, or push to `fix/manylinux-*` branches
-   - Builds wheels using cibuildwheel
-   - Tests installation on Ubuntu 22.04 (simulating Colab)
-
-2. **Local Testing**
-   ```bash
-   # Download built wheels
-   # Test in fresh environment
-   python -m venv test_env
-   source test_env/bin/activate
-   pip install leann_core-*.whl leann_backend_hnsw-*manylinux*.whl leann-*.whl
-   python -c "from leann import LeannBuilder; print('Success!')"
-   ```
