+Enter - toggle the tile text format
+
+UP,LEFT,DOWN,RIGHT / W,A,S,D / touchscreen swipes - move the tiles
+
+## Running instructions
+
+Compile & run the game with `./v run examples/2048`
+
+## Compiling to WASM
+
+1. Install Emscripten from:
+   https://emscripten.org/docs/getting_started/downloads.html
+
+2. Make sure that the environment in your shell is setup correctly,
+   i.e. that `emcc --version` works.
+
+   ```sh
+   . /opt/emsdk/emsdk_env.sh
+   emcc --version
+   ```
+
+3. Compile the game to WASM:
+   (the JS file contains a loader for the .wasm file, without the extension):
+   ```sh
+   v -prod -os wasm32_emscripten -o examples/2048/index.js examples/2048/
+   ```
+
+5. Run/test the game:
+
+   ```sh
+   emrun examples/2048/index.html
+   ```
+   
+   If you prefer, instead of `emrun`, you can start a simple V http file server:
+   ```sh
+   v -e 'import net.http.file; file.serve(folder: "examples/2048")'   
+   ```
+   and then open http://127.0.0.1:4001/ in your browser.
+
+Once you have opened the game in your browser, you can make changes to
+the V source, then recompile (step 3), and refresh the browser window
+with the game, to see their effect.
