Keep in mind that your project will not override your game files. You need to load the project files with ModEngine or backup your game directory and copy the project files over your game files so it takes effect.
Before we start, I'd like to recommend that you pick a map to work on, check its ID on DSMapStudio (On the Map Editor, left panel, there are maps with names and their respective IDs. For example: “m30_00_00_00” for High Wall of Lothric. We'll pick this one for this tutorial.)
You're now ready to start modding High Wall of Lothric. Every change will only be done in your project folder.
Go back to DSMapStudio, click on Map Editor, right click on “m30_00_00_00” and click Load Map. This is High Wall! Hold right mouse button (RMB) to control the camera, WASD (while holding RMB) to move, CTRL to slow down and SHIFT to speed up. You can control each individual speed by using your scroll wheel. Now, navigate to a place you know has a bonfire, for example the Tower on The Wall Bonfire.
Bonfires are comprised of the following things:

and paste it at the end.
If you want to “delete” another bonfire because you create other ones instead then simply open the “Map editor” in DS Map Studio and empty the “CollisionName” field for all related ojects. This will simply disable the bonfire. It's bad practice to delete original content. Disabling it is the better way.
