+* For Intel CPUs, you can use the following more specific command to check whether *hardware virtualization* is activated:
 
 ```
 cat /proc/cpuinfo | grep vmx

-* And this command for AMD CPUs
+* For AMD CPUs, the following command can be used:
 ```
 cat /proc/cpuinfo | grep svm

 * Look for `svm` for AMD-based processors, or `vmx` for Intel-based processors.
