 Changes to building LLVM
 ------------------------
 
-* ``llvm-min-tblgen`` is internally introduced to build LLVM public
-  headers. Note that ``llvm-tblgen`` depends on `GenVT.inc` that is
-  generated by ``llvm-min-tblgen``. Specify the external
-  ``llvm-tblgen`` for ``LLVM_TABLEGEN`` when you use prebuilt tablegen
-  tools, since ``llvm-tblgen`` is built as the superset of
-  ``llvm-min-tblgen``.
+* ``llvm-min-tblgen`` is introduced as a minimal subset of
+  ``llvm-tblgen``, whose purpose is to generate fragments of public
+  LLVM headers during LLVM builds. Building ``llvm-tblgen`` now
+  depends on ``GenVT.inc``, which is produced by
+  ``llvm-min-tblgen``. ``llvm-min-tblgen`` is an internal LLVM tool
+  which is not distributed. Users that rely on prebuilt tablegen tools
+  should use ``llvm-tblgen`` and ignore ``llvm-min-tblgen``.
