 ## Filing issues
 
 When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
 
-1. What version of Go are you using (`go version`)?
-2. What operating system and processor architecture are you using?
-3. What did you do?
-4. What did you expect to see?
-5. What did you see instead?

 General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
 The gophers there will answer or ask you to file an issue if you've tripped over a bug.
