 ### Custom LLVM Installation
 You can use the npm configuration options to set the path to the LLVM cmake directory. This is needed if you don't want to use the system default LLVM installation.
+(Formerly, `npm config` was used here. Meanwhile npm validates the config keys for being known and valid, and rejects custom keys.)
