 # Finding LLVM 
 The configuration script needs to find the llvm-config executable.
 There are three ways to specify this:
-1. Use --configure-args='--with-llvm-config=/path/to/llvm-config' in the call to `R CMD INSTALL ... Rllvm`
-1. Add the directory containing llvm-config to your PATH environment variable.
-2. Alternatively, set the environment LLVM_CONFIG to the fully-qualified name of the llvm-config
+ 1. Use --configure-args='--with-llvm-config=/path/to/llvm-config' in the call to `R CMD INSTALL ... Rllvm`
+ 1. Add the directory containing llvm-config to your PATH environment variable.
+ 2. Alternatively, set the environment LLVM_CONFIG to the fully-qualified name of the llvm-config
   executable  (including llvm-config at the end so that $LLVM_CONFIG refers to the executable, not the directory).
