-  + `m4` also needs a `-DGLSLANG_WEB` argument, or simply execute `updateGrammar web` from the glslang subdirectory
+  + execute `updateGrammar web` from the glslang subdirectory
+    (or if using your own scripts, `m4` needs a `-DGLSLANG_WEB` argument)
   + turn off the CMAKE options for `BUILD_TESTING`, `ENABLE_OPT`, and `INSTALL_GTEST`,
     while turning on `ENABLE_GLSLANG_WEB`
 * `emsdk` needs to be present in your executable search path, *PATH* for

 * Do not checkout SPIRV-Tools into `External`
   + Does not work correctly with emscripten out of the box and we don't want it
     in the build anyway. *TBD* Have build ignore SPIRV-Tools for web build
