 ### grub-btrfs
 
 
-This is a version 0.xx of grub-btrfs
-
-Version 1.xx release-candidate 
-https://github.com/Antynea/grub-btrfs/tree/v1.xx?files=1
+This is a version 1.xx of grub-btrfs
 
 #### Description
 
-grub-btrfs, add support for btrfs snapshots into grub menu
+grub-btrfs, Include btrfs snapshots at boot options. (grub menu)
 
-#### What does grub-btrfs v0.xx do :
+#### What does grub-btrfs v1.xx do :
 
-Simple rollback using snapshots you made previous.
+Simple rollback using snapshots you made previously.
 
-Makes a list of all snapshots, kernels, initramfs present on the filesystem and then creates a corresponding entered with name and date of snapshots in grub.cfg, which ensures a very easy rollback.
+- Automatically List snapshots existing on root partition (btrfs).
+- Automatically Detect kernel, initramfs and intel microcode in "/boot" directory on snapshots. (For custon name, see below.)
+- Automatically Create corresponding menuentry in grub.cfg , which ensures a very easy rollback.
 
-#### How to use it :
 
-1. Add lines to /etc/default/grub as needed, defaults listed as examples:
-2. 
-	* submenuname = name menu appear in grub ( e.g: GRUB_BTRFS_SUBMENUNAME="ArchLinux Snapshots" )
+#### How to use it:
 
-	* prefixentry = add a name ahead your snapshots entries ( e.g: GRUB_BTRFS_PREFIXENTRY="Snapshot" )
+Add this lines to /etc/default/grub:
 
-	* nkernel= name kernel you use it ( e.g: GRUB_BTRFS_NKERNEL=("vmlinuz-linux") )
+* GRUB_BTRFS_SUBMENUNAME="ArchLinux Snapshots" 					(Name menu appearing in grub.)
+* GRUB_BTRFS_PREFIXENTRY="Snapshot:"        		   			(Add a name ahead your snapshots entries.)
+* GRUB_BTRFS_NKERNEL=("vmlinuz-linux") 		 				(Use only if you have custom kernel name or auto-detect failed.)
+* GRUB_BTRFS_NINIT=("initramfs-linux.img" "initramfs-linux-fallback.img")	(Use only if you have custom initramfs name or auto-detect failed.)
+* GRUB_BTRFS_INTEL_UCODE=("intel-ucode.img") 					(Use only if you have custom intel-ucode or auto-detect failed.)
 
-	* ninit= name initramfs (ramdisk) you use it ( e.g: GRUB_BTRFS_NINIT=("initramfs-linux.img" "initramfs-linux-fallback.img") )
-
-	* intel_ucode= name intel microcode you use it ( e.g: GRUB_BTRFS_INTEL_UCODE=("intel-ucode.img") )
-
-2. Generate grub.cfg (on Archlinux is grub-mkconfig -o /boot/grub/grub.cfg )
+Generate grub.cfg (on Archlinux use grub-mkconfig -o /boot/grub/grub.cfg )
 
 grub-btrfs automatically generates snapshots entries.
 
-You will see it appear different entries, e.g : Prefixentry name of snapshot [2013-02-11 04:00:00]
+You will see it appear differents entries (e.g : Snapshot: my snapshot name overkill [2014-02-12 11:24:37])
 
-#### Warning
 
-Version 0.xx detect kernels,initramfs,intel microcode only in boot partition, not in snapshot.
-If kernels,initramfs,intel microcode, are present in boot partition but not in snapshot, entry will be created but not fonctional, you don't boot it.
+#### TO DO
 
-Version 1.xx will do it, release soon.
+* verify compatibility with manjaro and snapper (but I don't use them, so it will take some time)
