IK Rig

For the IK Rig, you can use the normal steps for creating one Automatically. However, it's important to know that the Automated Process may differ depending on your characters skeleton and that some characters from unknown sources may not work with this process since the Automated Setup requires that your character uses a Known skeletal structure. If your character does not use a known bone naming convention then the Automated Setup may fail or be incomplete. I would advise people using the Automated IK Rig Process to cross-reference their IK Rig with the one's provided in the Game Animation Sample Project. The Pelvis should be the root. The IK Rig Chain Settings should follow the same format as that of the UEFN IK Rig. When Setting up your IK Rig, cross reference it with that of the Target which is the UEFN, that's how you want yours setup as well.
