 You can simply start a period task with every 5 seconds immediately like this:
 
 ```clojure
-    (use 'ruiyun.tools.timer)
-    (run-task! #(println "Say hello every 5 seconds.") :period 5000)
+(use 'ruiyun.tools.timer)
+(run-task! #(println "Say hello every 5 seconds.") :period 5000)
 ```
 
 If you want delay the first run with 2 seconds：
 
 ```clojure
-    (run-task! #(println \"Say hello after 2 seconds.\") :dealy 2000)
+(run-task! #(println \"Say hello after 2 seconds.\") :dealy 2000)
 ```
 
 Use this if you want to execute a task at an absolute time：
 
 ```clojure
-    (run-task! #(println "Say hello at 2013-01-01T00:00:00 in beijing.") :at #inst "2013-01-01T00:00:00+08:00")
+(run-task! #(println "Say hello at 2013-01-01T00:00:00 in beijing.") :at #inst "2013-01-01T00:00:00+08:00")
 ```
 
 And, you can use the same timer in more than one tasks:
 
 ```clojure
-    (def greeting-timer (timer \"The timer for greeting\"))
-    (run-task! #(println \"Say hello after 2 seconds.\") :dealy 2000 :by greeting-timer)
-    (run-task! #(println \"Say hello every 5 seconds.\") :period 5000 :by greeting-timer)
+(def greeting-timer (timer \"The timer for greeting\"))
+(run-task! #(println \"Say hello after 2 seconds.\") :dealy 2000 :by greeting-timer)
+(run-task! #(println \"Say hello every 5 seconds.\") :period 5000 :by greeting-timer)
 ```
 
 Finally, you can cancel a timer's tasks:
 
 ```clojure
-    (cancel! greeting-timer)
+(cancel! greeting-timer)
 ```
