-### Git Hooks (Optional but Recommended)

-To ensure your code passes CI linting checks before pushing, install the pre-push hook:
-
-```bash
-cp scripts/hooks/pre-push .git/hooks/pre-push
-chmod +x .git/hooks/pre-push
-```
+1. To test your installation, you can try to build and run the example below:
+   ```bash
+   cmake -B build
+   cmake --build build --target silu_1_cols_1_channels_2048_tile_2048_run
+   ```
 
-The hook will run the same linting checks as CI:
-- License checks (reuse)
-- Python formatting (black)
-- C++ formatting (clang-format)
-
-To bypass the hook if needed: `git push --no-verify`
+Note: On a fresh install, if you get `CMake Error: Could not find CMAKE_ROOT !!!`, just deactivate and reactivate your python environment.
