+# Supported packages
+
+Basically any project that you can add via `add_subdirectory` should work with CPM.
+
+# Options
+
+If you set the CMake option `CPM_REMOTE_PACKAGES_ONLY` to `On`, packages will always be fetched via the URL. Setting `CPM_LOCAL_PACKAGES_ONLY` to `On` will only add packages via `find_package`.
