 Simple test which shows how to use hipify to port CUDA code to HIP.  Covered in more detail in blog.
 
 1. Add hip/bin path to the PATH  :
-    export PATH=$PATH:[MYHIP]/bin
+    <code>export PATH=$PATH:[MYHIP]/bin</code>
 
-2. hipify square.cu > square.cpp
+2. Do <code>$ hipify square.cu > square.cpp </code>
 
 3. Manually edit square.cpp to add hipLaunchParms lp to kernel parms:
-    vector_square(hipLaunchParm lp, T *C_d, const T *A_d, size_t N)
+    <code>vector_square(hipLaunchParm lp, T *C_d, const T *A_d, size_t N)</code>
 
     (see square.hipref.cpp for the correct output after running hipify and the above manual step)
