 ## Running
 ### Windows
 
-Copy `xsystem35.exe` to the game folder and run it.
+Execute `xsytem35`, and it will show a dialog to select a folder. Select the
+game folder (where the ALD files are located).
 
 ### Android

-## Usage
+## Use
 ### 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. A list of installed games will be displayed. Since no games
-   have been installed yet, only the "Install from ZIP" button will be visible.
-   Tap it.
-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.
+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.

+3. Select the ZIP file you created in 1.
+4. The game starts. To simulate right-click, tap the black bars on the left/right or top/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 end with a number
-  will be recognized as BGM files. For example:
+- Include all files in the `GAMEDATA` folder (`.ALD` files and others). `.EXE` and `.DLL` are not really needed, but you can include them as well.
+- Music files (`.mp3`, `.ogg` or `.wav`) whose file names end with a number are recognized as BGM files. For example:
   - `Track2.mp3`
   - `15.ogg`
-  - `rance4_03.wav` (Note: The filename shouldn't be `rance403.wav`, as it
-    would be treated as the 403rd track.)
+  - `rance4_03.wav` (This shouldn't be `rance403.wav`, because it would be treated as the 403rd track)
 
-Note: This ZIP format is also compatible with
-[Kichikuou on Web](http://kichikuou.github.io/web/).
+Note: This form of ZIP can be used in [Kichikuou on Web](http://kichikuou.github.io/web/) as well.
 
 ### 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.
+- You can export / import saved files using the option menu of the game list.
+- To uninstall a game, long-tap the 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.
