 ### Setting the keybord layout
 ```sh
 sed -i 's/us/dvorak/g' /etc/rc.conf
 ```
 The keymaps are listed in `/usr/share/kbd/keymaps`. If you are using a different keymap, then replace `dvorak` with that keymap. The keymap will be changed back to Gradma's keymap later.
+### Mounting filesystems
+Mount the filesystem.
+```sh
+mount <root partition> /mnt
+```
+Replace **\<root partition\>** with the root partition (ie. `/dev/sda3`).
 
+If you are using UEFI, mount the boot partition.
+```sh
+mkdir -p /mnt/boot/efi/
+mount <boot partiton> /mnt/boot/efi/
+```
+Replace **\<boot partition\>** with the boot partition (ie. `/dev/sda1`).
+
+Now prepare for `chroot`.
+```sh
+mount -t proc none /mnt/proc
+mount -t sysfs none /mnt/sys
+mount --rbind /dev /mnt/dev
+mount --rbind /run /mnt/run
+```
+Copy over network files.
+```sh
+cp /etc/resolv.conf /etc/hosts /mnt/
+```
+Now `chroot`.
+```sh
+chroot /mnt /bin/bash
+```
