In order for the edudu module to function properly, you will have to import the content-types provided in the export/ directory into your site. You will need the bundle_copy and ctools modules installed and enabled for this.

The github_resource content type (should have been called edudu_github_resource) should use auto_nodetitle.module to set the title to [node:field_edudu_github_user_or_org]
