+## On mirrorselect
+
+At some point during the installation process, you'll be asked to select your
+mirrors. Instead of using the handbook's method, use this instead to get the
+fastest available mirrors:
+
+```sh
+mirrorselect -s3 -b10 -D
+```
+
+This will take a bit of time, but will ping and download 100KB from each mirror
+and then choose the fastest 3 and append it to your `/etc/portage/make.conf`
+file.
