+# DungeonFogTileAssembler
+
+This application takes a folder of map tiles generated by [DungeonFog](https://dungeonfog.com) and attempts to assemble them into complete maps.
+
+## Input
+It expects the naming scheme to be `MapName_Tile_{n}_{x},{y}.ext` where `n` is the tile index, `x` is the horizontal position and `y` is the vertical position.
+
+The input folder can contain tiles from multiple different maps. They will all be assembled individually.
+
+If one or more tile images are missing the corresponding spots will be left as a blank black spot on the assembled map image.
+
+## Output
+A subfolder called `output` will be created and assembled maps will be put here. Finished maps will be named `MapName.ext`, where `MapName` is the first part of the tile name and `ext` is the extension of the tile images.
+
+## Libraries
+This program uses Pillow to assemble the images and PySimpleGUI to generate the interface and handle user input.
