+### Proposed features:
 
 We'll allow to add an item and mark it as done in one shot with the following syntax:
 
-<pre>
-todo.sh add x Helping colleague to install linux
-</pre>
+```bash
+$ todo.sh add x Helping colleague to install Linux
+```
 
-Why such a feature? Because some of us are using todo.sh to track all their activities, not only those which are planned for later therefore "to do". Why "x" and not just "do"? Because there is a big risk that some of the actual todos will start with "Do something...", and "x" comes from the "x" marker put on done items by "todo.sh do".

 And as we're hacking the "add" anyway, let's also allow to set a priority when adding an item using the following syntax:

-todo.sh add pri A "Need to write plugin example on Gina's wiki"
