 ### installation
 download library:
 
-  mkdir ~/lib && cd ~/lib
-  git clone git://github.com/mpapis/backup_sh.git
+    mkdir ~/lib && cd ~/lib
+    git clone git://github.com/mpapis/backup_sh.git
 
 add to your ~/.bash_rc file:
 
-  export PATH=$PATH:~/lib/backup_sh
+    export PATH=$PATH:~/lib/backup_sh
 
 ### usage
 create simple bash script ~/lib/backup_sh/backup_something.sh:
 
-  #!/bin/bash
-
-  source ~/lib/backup_sh/backup.sh
-  backup_dir ~/backups
-
-  NAME=your_db_name
-  SUFFIX=db
-  dump_mysql
-  rotate 3
+    #!/bin/bash
+    
+    source ~/lib/backup_sh/backup.sh
+    backup_dir ~/backups
+    
+    NAME=your_db_name
+    SUFFIX=db
+    dump_mysql
+    rotate 3
 
 add execution rights to the new script:
 
-  chmod +x ~/lib/backup_sh/backup_something.sh
+    chmod +x ~/lib/backup_sh/backup_something.sh
 
 make a test run of backup:
 
-  ~/lib/backup_sh/backup_something.sh
+    ~/lib/backup_sh/backup_something.sh
 
 add a cron job to run the script:
 
-  crontab -e
+    crontab -e
 
 you probably got an vim editor so press `i` for editing mode and paste this line
 
-  6 0 * * * ~/lib/backup_sh/backup_something.sh
+    6 0 * * * ~/lib/backup_sh/backup_something.sh
 
 and save the changes by pressing `ESC :wq` (vim editor), this will call the backup everyday at 6am.
