 As an example, the [Scaladex project](https://github.com/scalacenter/scaladex) (for the code behind the website) uses the label "low-hanging fruit" to mark beginner-friendly issues in Github so this label can be set by the maintainer in the edit project page and all the [issues with this label](https://github.com/scalacenter/scaladex/labels/low-hanging%20fruit) will be stored for this project. It also has a [gitter room](https://gitter.im/scalacenter/scaladex) for chatting and a [contributing guide](https://github.com/scalacenter/scaladex/blob/master/CONTRIBUTING.md) which will be auto-populated for the project when all the projects are indexed.
 
-Scaladex uses Github's [GraphQL API](https://developer.github.com/v4/) to get a project's beginner-friendly issues, see the [Github Topics](#github-topics) section below for more info about Github's GraphQL API. To get a project's contributing guide, Scaladex uses Github's [REST API](https://developer.github.com/v3/) to send a GET request to the [Community Profile API](https://developer.github.com/v3/repos/community/) which will return links to a project's contributing guide, code of conduct and license. Lastly, to get a project's chatroom, Scaladex generates a URL for a project's gitter room based on the project's repository name and the organization it belongs to (Ex. <https://gitter.im/scalacenter/scaladex>) and checks if that URL exists.

 You can also find Contributing Info on the front page of Scaladex. Now, Scaladex highlights a random subset of projects which have Contributing Info on the front page of Scaladex. It picks a random selection of projects each time the page is loaded to give the same amount of exposure to all projects with Contributing Info. We hope to highlight and better guide potential contributors to projects and issues that are of interest to them!
