Where can I get information on creating a Discharge Packet?

I was recently accepted into the Chaplain Candidate Program while currently on active duty. I have been trying to start the discharge paperwork, but I am not permitted to because of "my place of duty." Being accepted into the program, while active duty, means that I will not get my orders until I have been discharged. I cannot find anything online, after various searches, about what documentation is needed to begin a discharge packet. I have 4187 and a 368 signed by the respective approving authorities. I have not been able to get guidance from my first line due to the busy nature of the training room. I was wondering if someone could provide some guidance on the subject so that I may complete this.
