 ### Compiling
 * Now you can compile as follows (With `MY_NEW_MEDUSA` your MEDUSA config if you want/need to create one) : 
   ```sh 
-  ./makenemo -m X86_ARCHER2-Gnu -r ORCA2_MEDUSA -n ${MY_NEW_MEDUSA} -j 16 
+  ./makenemo -m X86_ARCHER2-Gnu_4.2 -r ORCA2_MEDUSA -n ${MY_NEW_MEDUSA} -j 16 
   ```
 * Subsequently when you compile you can instead run :
   ```sh
-  ./makenemo -m X86_ARCHER2-Gnu -r ${MY_NEW_MEDUSA} -j 16
+  ./makenemo -m X86_ARCHER2-Gnu_4.2 -r ${MY_NEW_MEDUSA} -j 16
   ```
