+
+### Start
+Start will run a command in the background and return the pid immediately.
+
+It takes the same command arguments as `#run`
+
+The parent process (you) will not wait for the child to finish or return any information.
+
+This is useful if you want to run a command, but dont care about the output or exit status.
+
+__BEWARE__ of long running commands that could fail.  ShellTastic detaches itself from the child command.
+
+
+
+```ruby
+ShellTastic::Command.start("sleep 10; date")
+```
+or
+
+```ruby
+ShellTastic::Command.start(["sleep 10", "date"])
+```
+
+The above will return an Array of hash meta-data.
+
+```ruby 
+[{ :output, :pid, :error, :start, :stop, :total_time, :exitstatus, :command }]
+```
+
+For example, the above command's return would look something like this:
+
+```ruby
+[
+  { 
+    :output=>nil, 
+    :pid=>17507, 
+    :error=>false, 
+    :start=>2013-02-03 17:41:45 -0500, 
+    :stop=>2013-02-03 17:41:45 -0500,
