 # Go Report Card
 
-A web application that generates a report on the quality of an open source go project. It uses several measures, including `gofmt`, `go vet`, `go lint` and `gocyclo`. To get a report on your own project, try using the hosted version of this code running at [goreportcard.com](http://goreportcard.com). Currently this is limited to projects hosted on GitHub, but there is an [open issue](https://github.com/gojp/goreportcard/issues/51) to support all publicly hosted repos.
