-## Build
+## Usage
+### Basic Usage
+1. Create a ZIP file containing all the game files and BGM files (see
+   [below](#preparing-a-zip) for details), and transfer it to your device.
+2. Open the app. Tap the option menu (three dots in the top right corner) and
+   select "Install from ZIP".
+3. Select the ZIP file you created in step 1.
+4. The game will start. To simulate a right-click, tap the black bars on either
+   the left or right, or top or bottom of the screen.
+
+### Preparing a ZIP
+- Include all files from the `GAMEDATA` folder (such as `.ALD` files and
+  others). `.EXE` and `.DLL` files are not necessary, but you can include them
+  if you want.
+- Music files (`.mp3`, `.ogg`, or `.wav`) whose filenames have a number either
+  at the beginning or just before the extension are recognized as BGM files.
+  For example:
+  - `Track2.mp3`
+  - `15.ogg`
+  - `02 - Title.mp3`
+  - `rance4_03.wav` (Note: The filename shouldn't be `rance403.wav`, as it
+    would be treated as the 403rd track.)
+
+Note: This ZIP format is also compatible with
+[Kichikuou on Web](http://kichikuou.github.io/web/).
+
+### Miscellaneous
+- You can export or import save files via the game list's option menu.
+- To uninstall a game, long-tap its title in the game list.
+
+## Known Issues
+- Android versions older than 7.0 cannot handle ZIP files containing Shift-JIS
+  filenames. This issue occurs with some ZIP files distributed on
+  [retroc.net](http://retropc.net/alice/). If you encounter the error message
+  "This type of ZIP is not supported," unzip the file on your PC and re-archive
+  it using modern ZIP creation software.
