 If you are working with non-human data, you will need to register with an NCBI repository such as GEO or SRA.

+Prospective AnVIL data submitters should complete the [AnVIL Dataset Onboarding Application](https://docs.google.com/forms/d/e/1FAIpQLSdK_r1DTb_bBUiG9IvY5hwJ4Y-LHoaXk-E4L98MRcLR2TTtcQ/viewform) for review by the AnVIL leadership committee.    
+
+### Before you apply    
+Note that you will need the **phsID** from **dbGap** (step 1.2 above) and **Access Rrstrictions** (i.e., Data Use limitations/consent groups) to complete the application.  
+
+### Access Restrictions
+Known Data Use Limitations (DUL) - the list of requirements for gaining access and using the data - need to be clearly defined by the data depositor. This is completed via the NIH Institutional Certification form signed by the submitter's institutional official and provided directly to the Genomic Program Administrator for the IC (i.e,. NHGRI).   
+
+You should include your DULs as part of the AnVIL onboarding application. Consent information, along with other information listed in this spreadsheet, are documented in DUOS. Once ingested into TDR, DUOS will handle all protocols for gaining access.
+
+<Alert severity="warning">
+    Please contact your program officer and the NHGRI Genomic Program Administrator for assistance and/or questions about dbGaP registration and/or consent groups.
