+LÖVE Switch Port
+==================
+
+<p align="center"><img src="icon.jpg"></p>
+
+## Usage
+
+### Running game
+
+Put a LÖVE archive named `game.love` in the same folder as the NRO file of the latest release.
+Additionally, you can directly drop the contents of the archive in the folder, as long as it contains a `main.lua` file.
+
+## Development
+
+### Build dependencies
+
+For building, you need the devkitA64 from devkitPro setup, along with switch portlibs and libnx.
+Documentation to setup that can be found [here](https://switchbrew.org/wiki/Setting_up_Development_Environment).
+
+### Packaging games
+
+To produce self-contained game NRO files, download the latest release, and run the following commands:
+
+```
+# Customize $APP_* vars to your liking
+
+mkdir romfs
+cp game.love romfs/game.love # Your game here
+"$DEVKITPRO/tools/bin/nacptool" --create "$APP_TITLE" "$APP_AUTHOR" "$APP_VERSION" game.nacp
+"$DEVKITPRO/tools/bin/elf2nro" love.elf "game.nro" --icon="$APP_ICON" --nacp="game.nacp" --romfsdir="romfs"
+```
+
+### Compiling from source
+
+Run one the following command from the project root to build:
+
+```
+./build.sh
+```
+
+NRO and ELF files will be located in the `dist` folder.
+
+## Known limitations
+
+* VI Layer creation error when changing video modes, use conf.lua to set a resolution 
+* Message boxes do nothing more than being logged to stdout
