+## Testing Conan Integration
+
+To verify that Conan is properly integrated and working:
+
+```bash
+# Run the Conan integration test
+./scripts/test-conan-build.sh
+```
+
+This test script will:
+1. Verify Conan installation
+2. Check/create Conan profile
+3. Install dependencies
+4. Generate Conan toolchain
+5. Configure CMake with Conan
+6. Validate the integration
+
 ## Troubleshooting
 
+### Conan Not Found
+If you get "conan: command not found":
+```bash
+# Install Conan
+pip3 install conan
+
+# Verify installation
+conan --version
+
+# Create profile
+conan profile detect --force
+```
+
+### Conan Profile Issues
+If Conan complains about missing profile:
+```bash
+# Detect and create default profile
+conan profile detect --force
+
+# Verify profile exists
+conan profile show default
+```
+
+### Conan Toolchain Not Found
+If CMake can't find the Conan toolchain:
+```bash
+# Make sure to run conan install first
+conan install . --build=missing
+
+# The toolchain will be at: build/Release/generators/conan_toolchain.cmake
+# Use it with: cmake .. -DCMAKE_TOOLCHAIN_FILE=../build/Release/generators/conan_toolchain.cmake
+```
+
 ### Cross-Compiler Not Found
 If you get errors about missing cross-compiler:
 1. Check that x86_64-elf-gcc is in your PATH

 - ✅ Version management
 - ✅ Cross-platform package management
 - ✅ Integration with CMake and other build systems
+- ✅ **Recommended for CI/CD** - ensures consistent builds
 
 #### Disadvantages
 - ❌ Requires Python and Conan
-- ❌ Additional complexity
-- ❌ Currently overkill (we have no dependencies yet)
+- ❌ Additional setup step
 - ❌ Learning curve
 
+#### When to Use
+- ✅ **CI/CD pipelines** (all workflows now use Conan)
+- ✅ **Production builds** requiring reproducibility
+- ✅ **When adding external dependencies** (QT6, Mesa RADV in the future)
+- ✅ **Cross-platform development** needing consistent dependencies

 ### For CI/CD
-**Use: Make or CMake**
+**Use: Conan + CMake (Recommended)**
 ```bash
 # GitHub Actions, GitLab CI, etc.
-make all && make test
-
-# Or with CMake
-cmake -B build -G Ninja
