-- **Copy the single header**, as described [below](#header-only) — no build-system integration required.
-- **CMake**: use [`find_package()`](cmake.md#external) if the library is already installed,
-  [`add_subdirectory()`](cmake.md#embedded) to embed the source tree, or [`FetchContent`](cmake.md#fetchcontent) to
-  download it at configure time; see [CMake](cmake.md).
-- **Package managers**: install the library with a package manager such as Homebrew, Conan, or vcpkg; see
-  [Package Managers](package_managers.md).
-- **pkg-config**: if you use bare Makefiles instead of CMake, [pkg-config](pkg-config.md) can supply the include flags

+- **Single header**: copy [`json.hpp`](#header-only) into your project; no build-system integration required.
+- **CMake**, see [CMake](cmake.md):
+    - [`find_package()`](cmake.md#external) if the library is already installed;
+    - [`FetchContent`](cmake.md#fetchcontent) to download it at configure time (CMake 3.14 or later);
+    - [`add_subdirectory()`](cmake.md#embedded) to embed a vendored copy of the source tree;
+    - or [support both](cmake.md#supporting-both) with an option that selects installed or vendored.
+- **Package managers**: install the library with Homebrew, Conan, vcpkg, or one of the many others; see
+  [Package Managers](package_managers.md) for the full list.
+- **pkg-config**: if you use bare Makefiles instead of CMake, [pkg-config](pkg-config.md) supplies the include flags
   for an already-installed library.
 
 Once the library is integrated, see the [Migration Guide](migration_guide.md) for how to keep your code future-proof
