How to: Setup Oauth Token
Hacktoberfest uses `GITHUB_CLIENT_ID` & `GITHUB_CLIENT_SECRET` variables to configure OmniAuth.

This allows users to be authorized for Hacktoberfest via Github.

For this, you will have to create a Github OAuth App (https://developer.github.com/apps/building-oauth-apps)

Be sure your OAuth app is configured with the following URLs

![Oauth Config](https://user-images.githubusercontent.com/7976757/66855839-fd259980-ef51-11e9-808b-26a9251841bf.png)

> Homepage URL: `http://localhost:3000`\
> Authorization callback URL: `http://localhost:3000/auth/github/callback`

The Client ID and Client Secret are right above this configuration. Use them to set the following ENV variables: 

```
GITHUB_CLIENT_ID=
GITHUB_CLIENT_SECRET=
```
