    Kernel labs: use make kernelversion
    
    Use make kernelversion to check kernel version (But also mention that
    this information is visible in the Makefile).

 As we will do our labs with the Linux 5.10 stable branch, the remote branch
 we are interested in is \code{remotes/stable/linux-5.10.y}.
 
-First, open the \code{Makefile} file just to check the Linux kernel
-version that you currently have.
+First, execute the following command to check which version you
+currently have:
+
+\begin{verbatim}
+make kernelversion
+\end{verbatim}
+
+You can also open the \code{Makefile} and look at the beginning of it
+to check this information.
 
 Now, let's create a local branch starting from that remote branch:
 \begin{verbatim}
 git checkout -b 5.10.bootlin stable/linux-5.10.y
 \end{verbatim}
 
-Open \code{Makefile} again and make sure you now have a 5.10.y version.
+Check the version again using the \code{make kernelversion} command
+to make sure you now have a 5.10.y version.
