Step 2: Create a Warsword folder in your Warband/modules folder.
Step 3: Unpack the mod zip into that folder it using WinRAR or 7zip.
Step 4: Go to your main M&B Warband folder, locate the file called "mb_warband" and either put it somewhere else or rename it EG. "mb_warband_original"
Step 5: Enter the mod's folder (the one you put inside Modules) and enter the first folder (1.170 exe). Copy the file you find there and paste it inside your M&B Warband folder.
Now you should have "mb_warband" (the one you just put there) and the other file you renamed (if you didn't put it elsewhere).
Step 6: Go in the mod's folder (the one inside Modules) and enter the folder named WSE.
Step 7: Transfer the contents of that folder to your main Warband folder (where mb_warband.exe is located).
Step 8: Launch the launcher once using mb_warband.exe, then close it before starting a game.
Step 9: Launch the game from the WSE Loader every time from now on. Select the mod in the drop menu in the launcher and then launch the mod.
