After some 8 | discussion on [golang-challenge Slack channel](https://gophers.slack.com/messages/golang-challenge/), 9 | this project was born as a community effort to improve this process. 10 | 11 | The basic idea is to take some inspiration from [exercism.io](http://exercism.io/) project, 12 | and build a similar command line driven workflow for Go challenge. Of course, given a more 13 | restrictive nature of the challenge itself (compared to exercism.io's free-flow exercises), 14 | we'll have to modify bits and piece to make it fit the rules of the challenge. 15 | 16 | # How to contribute 17 | 18 | * [golang-challenge Slack channel](https://gophers.slack.com/messages/golang-challenge/) is the main 19 | discussion channel for this project - feel free to jump in and talk to people there. 20 | 21 | * [Github issues](https://github.com/GoChallenge/gochallenge/issues) - 22 | alternatively, if you have an idea that you want to discuss, feel free to open an 23 | issue on this project, and start the discussion. 24 | -------------------------------------------------------------------------------- /api/auth/github.go:
