How to use

  1. Build a portal frame in the Overworld, but do not light it yet.
  2. Press F3 while standing in the frame, note the coordinates, and fill them into the Overworld section above.
  3. The Nether coordinates on the right will be calculated automatically.
  4. Light the Overworld portal and go into the Nether.
  5. Go to the Nether coordinates: (0, 65, 0).
  6. Place an obsidian block at that position, build a new portal around it, and light it.
  7. Disable the old Overworld portal so your link always stays consistent.
  8. Use the new Nether portal to return to the Overworld at the exact linked location.
