     - Fault injection is one of testing techniques.
       It makes easier to test your application's error handling behavior or
       to improve the coverage of your tests.
       See http://en.wikipedia.org/wiki/Fault_injection for more details.
 
+  * What can I do with fault_injection.rb ?
+
+    - You can raise error at any line of code or particular method call
+      without changing the target code.
+  * Cat it be used with Ruby on Rails testing?
+
+    - It should, but it's not yet tested well with big applications.
+      Please try and feel free to send me a bug report.
+
   * Can I use it in my application code?
 
     - No. It is for your testing code.
 
   * Can I use it everywhere in my test code?
 
     - You should not. It is for some limited situation that rarely
       happen or difficult to set up (ex. IOError).
       If you can make 'evil situation' easily, that's better ;)
+      
+      In addition, fault_injection.rb uses set_trace_func API of ruby and
+      it makes a script much slower.
