+Default is to use GNU runtime `TC_CXX_RUNTIME = "gnu"` which consists of libgcc, libstdc++ to provide C/C++
 runtime support. However it's possible to use LLVM runtime to replace it where
 compile-rt, llvm libunwind, and libc++ are used to provide C/C++ runtime, while
 GNU runtime works with both GCC and Clang, LLVM runtime is only tested with Clang
 compiler, switching to use LLVM runtime is done via a config metadata knob
 
 ```shell
-RUNTIME = "llvm"
+TC_CXX_RUNTIME = "llvm"
 ```

+TC_CXX_RUNTIME variable influences individual runtime elements and can be set explicitly as well
 e.g. `LIBCPLUSPLUS` `COMPILER_RT` and `UNWINDLIB`.
 
 Please note that this will still use crt files from GNU compiler always, while llvm now
 do provide crt files, they have not been yet integrated into the toolchain.
