 # How to use the LTFS (Quick start)
 
-This section is for person who already have a machine the LTFS is installed. Instruction how to use the LTFS is also available on [Wiki](https://github.com/LinearTapeFileSystem/ltfs/wiki).

 ## Step1: List tape drives
 
 `# ltfs -o device_list`
 
-The output is like follows. You can have 3 drives in this example and you can use "Device Name" field, like `/dev/sg43` in this case, as the argument of ltfs command to mount the tape drive.

 ## Step2: Format a tape
 
-As described into the LTFS format specifications, LTFS uses the partition feature of the tape drive. It means you can't use a tape just after you purchase a tape. You need format the tape before using int on LTFS.

 To format a tape, you can use `mkltfs` command like
 
 `# mkltfs -d 9A700L0077`
 
-In this case, `mkltfs` tries to format a tape in the tape drive `9A700L0077`. You can use a device name `/dev/sg43` instead.

 ## Step3: Mount a tape through a tape drive
 
 After you prepared a formatted tape, you can mount it through a tape drive like
 
 `# ltfs -o devname=9A700L0077 /ltfs`
 
-In this command, the ltfs command try to mount the tape in the tape drive `9A700L0077` to `/ltfs` directory. Of cause, you can use a device name `/dev/sg43` instead.
+In this command, the ltfs command will try to mount the tape in the tape drive `9A700L0077` to `/ltfs` directory. Of course, you can use a device name `/dev/sg43` instead.
 
-If mount process is successfully done, you can access to the LTFS tape through `/ltfs` directory.

 You must not touch any `st` devices while ltfs is mounting a tape.
 
 ## Step4: Unmount the tape drive
 
-You can use following command when you want to unmount the tape. The ltfs command try to write down the current meta-data to the tape and close the tape cleanly.

 ## The `ltfsee_ordered_copy` utility
 
 The [`ltfsee_ordered_copy`](https://github.com/LinearTapeFileSystem/ltfs/wiki/ltfs_ordered_copy) is a program to copy files from source to destination with LTFS  order  optimization.
 
-It is written by python and it can work on both python2 and python3 (Python 2.7 or later is strongly recommended). You need to install the `pyxattr` module for both python2 and python3.
