 ## Description
 Actually, Getch support only the [AMD64 handbook](https://wiki.gentoo.org/wiki/Handbook:AMD64) and only with the last `stage3-amd64-systemd`.  
-It also require a disk (only one for now) with a minimum of 20G.  
 
 BIOS system will use `Grub2` and `systemd-boot` for UEFI. Filesystem supported by Getch are for now:
 + Ext4
 + LVM

 When you boot from an `iso`, you can install `ruby`, `getch` and correct your `PATH=` directly with the `bin/setup.sh`:
 
     # sh <(curl -L https://raw.githubusercontent.com/szorfein/getch/master/bin/setup.sh)
     # source ~/.zshrc # or ~/.bashrc
 
+If you want to try the master branch:
+
+    # git clone https://github.com/szorfein/getch
+    # cd getch
+    # ruby -I lib bin/getch -h

 ## Troubleshooting
 
 #### LVM
-Unless your old LVM volume group is also named `vg0`, `getch` may fail to partition your disk. You have to clean up your device before proceed with `vgremove` and `pvremove`.
+Unless your old LVM volume group is also named `vg0`, `getch` may fail to partition your disk. You have to clean up your device before proceed with `vgremove` and `pvremove`. An short example how doing this with a volume group named `vg0`:
 
+    # vgdisplay | grep vg0
+    # vgremove -f vg0

 #### Encryption enable on BIOS with ext4
 To decrypt your disk on BIOS system, you have to enter your password two times. One time for Grub and another time for the initramfs (Genkernel). [post](https://wiki.archlinux.org/index.php/GRUB#Encrypted_/boot).  
 Also with GRUB, only a `us` keymap is working.
 
 #### With ZFS
-When you boot, the pool may fail to start, it's happen when the pool has not been `export` to the ISO. So just reboot on your ISO:
+When Gentoo boot, the pool may fail to start, it's happen when the pool has not been `export` to the ISO. So just reboot on your ISO:
 
-    # zpool import -N -R /mnt zpool
+You need the partuuid, pool are create with the first 5 characters, just replace `sdX` by your real device:
+
+    # ls -l /dev/disk/by-partuuid/ | grep sdX4
+    -> 150ed969...
+    # zpool import -N -R /mnt rpool-150ed

+And export them correctly:
+
     # zpool export -a
 
-And it's all.
+It's all.
