 ### Dependencies
 
 Dependencies are managed via custom `Find*.cmake` scripts in `deps/`.
-These scripts use `FetchContent` under the hood to download and build
+See `/skill:cmake` for adding new dependencies.
-libraries automatically.
-
-To add a new dependency:
-
-1. Add the corresponding `Find<name>.cmake` to `deps/`
-2. Add `find_package(<name> REQUIRED)` to `CMakeLists.txt`
-3. Link with `<name>::<name>` in `target_link_libraries()`
-
-### CMake Module Path
-
-`deps/` is added to `CMAKE_MODULE_PATH` so `find_package()` resolves
-to the custom scripts instead of system-installed packages.
