### Summary
1. If Luanti is running, shut it down
2. Trust the code. In the settings menu or `minetest.conf`, add `tutorial_mapgen` to `secure.trusted_mods`

5. Start Luanti and create a new world and enter the world in singleplayer (there should be a confirmation message in chat)
6. Edit the map to your likings
7. Grant yourselves the `tutorialmap` privilege
8. Use `/tsave` command to save the map

### Testing and finalizing
To test your new map, remove the 2 `minetest.conf` settings and create a new world and check if everything works. If it does work, you can commit your changes now.
(Note: The `/tsave` command is not available if the `tutorial_mapgen` mod failed to request an "insecure" environment due to mod security issues.)
