   \begin{itemize}
-    \item Run it in the main kernel source directory!
-    \item Remember to run multiple jobs in parallel
-          if you have multiple CPU cores / threads. Our advice:
-          \code{ncpus * 2} or \code{ncpus + 2}, to fully load
-          the CPU and I/Os at all times.\\
+    \item Only works from the top kernel source directory
+    \item Should not be performed as a priviledged user
+    \item Run several jobs in parallel. Our advice: \code{ncpus * 2} to
+      fully load the CPU and I/Os at all times.\\
           Example: \code{make -j 8}
-    \item No need to run as root!
     \item To {\bf re}compile faster (7x according to some benchmarks),\\
 	  use the \code{ccache} compiler cache:\\
           \code{export CROSS_COMPILE="ccache arm-linux-"}
