It is the work of hundreds of contributors. We appreciate your help!
## 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.
