Hello @tj513,
Please add your GitHub ID to your profile. There’s a field in https://talk.openmrs.org/users/tj513/preferences in your case.
I’m sure you already went through the Getting Started guide at https://wiki.openmrs.org/display/docs/Getting+Started+as+a+Developer.
The project you’ve chosen has a dedicated page at GSOC 2017 FHIR Module Enhancements Project. You can talk with the assigned mentor there.
Hope this helps!
