 ### macOS
 
 You will need to have 2 environment variables set to do the build:
 
-    LLVM_ROOT - This points to the root of the LLVM source tree.
-    LLVM_BUILD_ROOT - This points to the root of an LLVM build directory. This may be the same as the LLVM source tree, especially if you're working from a binary install.

 For now, you will have to set an @rpath manually on your executables so that they can find the LLDB.framework at runtime. This can be done with install_name_tool:
 
-install_name_tool -add_rpath /Applications/Xcode.app/Contents/SharedFrameworks target/debug/examples/barebones
+    install_name_tool -add_rpath /Applications/Xcode.app/Contents/SharedFrameworks target/debug/examples/barebones
