 The ``TARGETS`` form specifies rules for installing targets from a
-project.  There are several kinds of target files that may be installed:
+project.  There are several kinds of target :ref:`Output Artifacts`
+that may be installed:
 
 ``ARCHIVE``
-  Static libraries are treated as ``ARCHIVE`` targets, except those
-  marked with the ``FRAMEWORK`` property on macOS (see ``FRAMEWORK``
-  below.) For DLL platforms (all Windows-based systems including
-  Cygwin), the DLL import library is treated as an ``ARCHIVE`` target.
-  On AIX, the linker import file created for executables with
-  :prop_tgt:`ENABLE_EXPORTS` is treated as an ``ARCHIVE`` target.
+  Target artifacts of this kind include:
+
+  * *Static libraries*
+    (except on macOS when marked as ``FRAMEWORK``, see below);
+  * *DLL import libraries*
+    (on all Windows-based systems including Cygwin; they have extension
+    ``.lib``, in contrast to the ``.dll`` libraries that go to ``RUNTIME``);
+  * On AIX, the *linker import file* created for executables with
+    :prop_tgt:`ENABLE_EXPORTS` enabled.
 
 ``LIBRARY``
-  Module libraries are always treated as ``LIBRARY`` targets. For non-
-  DLL platforms shared libraries are treated as ``LIBRARY`` targets,
-  except those marked with the ``FRAMEWORK`` property on macOS (see
-  ``FRAMEWORK`` below.)
+  Target artifacts of this kind include:
+
+  * *Shared libraries*, except
+
+    - DLLs (these go to ``RUNTIME``, see below),
+    - on macOS when marked as ``FRAMEWORK`` (see below).
 
 ``RUNTIME``
-  Executables are treated as ``RUNTIME`` objects, except those marked
-  with the ``MACOSX_BUNDLE`` property on macOS (see ``BUNDLE`` below.)
-  For DLL platforms (all Windows-based systems including Cygwin), the
-  DLL part of a shared library is treated as a ``RUNTIME`` target.
+  Target artifacts of this kind include:
+
+  * *Executables*
+    (except on macOS when marked as ``MACOSX_BUNDLE``, see ``BUNDLE`` below);
+  * DLLs (on all Windows-based systems including Cygwin; note that the
+    accompanying import libraries are of kind ``ARCHIVE``).
 
 ``OBJECTS``
-  Object libraries (a simple group of object files) are always treated
-  as ``OBJECTS`` targets.
+  Object files associated with *object libraries*.
 
 ``FRAMEWORK``
   Both static and shared libraries marked with the ``FRAMEWORK``
