+# GitHub Actions CI
+
+This directory contains the GitHub Actions workflow for the fet library.
+
+## CI Workflow (ci.yml)
+
+The CI workflow runs on every push and pull request to main/master branches and includes:
+
+### Build Matrix
+- **Operating Systems**: Ubuntu, Windows, macOS
+- **Compilers**: GCC, Clang, MSVC
+- **Language Standard**: C++14
+
+### Build Steps
+1. **Environment Setup**: Installs compilers and dependencies (Boost)
+2. **Missing Dependencies**: Creates bind_front.hpp for C++14 compatibility
+3. **Compilation Test**: Verifies all headers compile without errors
+4. **Execution Test**: Runs simple test to verify basic functionality
+
+### Code Quality Checks
+1. **Format Check**: Validates code formatting using uncrustify
+2. **Header Independence**: Ensures each header can be compiled standalone
+
+### Dependencies
+- **Boost**: Required for some headers (logic/tribool, fusion)
+- **bind_front.hpp**: Custom C++14 implementation (auto-generated)
+
+The workflow is designed specifically for header-only libraries and focuses on compilation validation across multiple platforms and compilers.
