 This file contains and points to instructions about building GDAL from source.
 
-# Building with cmake
+# Building with cmake (GDAL >= 3.5.0)
+
+CMake is the only build system supported since GDAL 3.6.0.
 
 There is a [build hints](https://gdal.org/build_hints.html) page on the website.
 
 Beyond that page, note:
   - cmake builds in the source directory are not supported (expected to fail)
 
-# Building with autoconf
+# Building with autoconf or nmake (GDAL < 3.6.0)
 
-Building with autoconf is deprecated.  While there are many --with
-options, the build system mostly follows autoconf norms.
+autoconf and nmake build systems were only available in GDAL < 3.5.0, have
+been deprecated in GDAL 3.5.x, and finally completely removed in GDAL 3.6.0.
